maximum productivity calculus

Calculus Calculus: An Applied Approach (MindTap Course List) The production function for a manufacturer is given by f ( x , y ) = 60 x 0.7 y 0.3 where x is the number of units of labor (at $42 per unit) and y is the number of units of capital (at $144 per unit). Step 1: Set profit to equal revenue minus cost. State the necessary conditions. The function has an absolute minimum over [0,2),[0,2), but does not have an absolute maximum over [0,2).[0,2). Explain how to find the critical points of a function over a closed interval. Pre-Algebra, Algebra, Pre-Calculus, Calculus, Linear Algebra math help. Since this limit exists, both one-sided limits also exist and equal f′(c).f′(c). Note that if ff has an absolute extremum at cc and ff is defined over an interval containing c,c, then f(c)f(c) is also considered a local extremum. Search for: 4.3 Maxima and Minima. Register. Available online 24/7 (even at 3AM) Cancel subscription anytime; no obligation . Appendix: The Unit Circle . It’s quite common to have a problem involving a function without an attached graph, so it can be useful to know the method behind getting these values. Calculus Volume 1. In precalculus, you learned a formula for the position of the maximum or minimum of a quadratic equation y=ax2+bx+c,y=ax2+bx+c, which was h=−b(2a).h=−b(2a). Therefore the function has a maximum value at (-1/3, 29/27). Before looking at how to find absolute extrema, let’s examine the related concept of local extrema. What was the amount of gold produced during this minimum? Calculus I: Maximum and Minimum Values Peng Li [email protected] January 5, 2021 Peng Li ( [email protected] ) Calculus I: Maximum and Minimum Values January 5, 20211/11. The production of gold can be modeled by G(t)=(25t)(t2+16),G(t)=(25t)(t2+16), where tt is the number of years since the rush began (0≤t≤40)(0≤t≤40) and GG is ounces of gold produced (in millions). MTH 210 Calculus I Chapter 4: Applications of Derivatives ... For the following exercises, consider the production of gold during the California gold rush (1848–1888). Max/Min Applications. There are two ways to find maximum profit: with a graph, or with calculus. Second, if a function ff has an absolute extremum over an interval II at c,c, the absolute extremum is f(c).f(c). Productivity is a measure of a company’s efficiency regarding the production process. For a function to be a maximum (or minimum) its first derivative is zero. In fact, if ff has a local extremum at a point x=c,x=c, the derivative f′(c)f′(c) must satisfy one of the following conditions: either f′(c)=0f′(c)=0 or f′(c)f′(c) is undefined. A summary of the data is shown in the following figure. Consider the function ff shown in Figure 4.14. In these cases, how can we use a formula for a function to determine where these extrema occur? Find the maximum production level for this manufacturer. This value means that there is either a maxima or a minima at t = 1/4. A maximum is a high point and a minimum is a low point: In a smoothly changing function a maximum or minimum is always where the function flattens out (except for a saddle point). Consider the function f(x)=x2+1f(x)=x2+1 over the interval (−∞,∞).(−∞,∞). Draw a graph to support your explanation. Step 4: Compare the results. Later in this chapter we look at analytical methods for determining whether a function actually has a local extremum at a critical point. In Figure 4.15, we see several different possibilities for critical points. Many graphs have certain points that we can identify as ‘maxima‘ and ‘minima‘, which are the highest or lowest points on a graph. When p = 200, R (p) = $ 0. At x = -1/3, 24x + 4 = -4, which is less than zero. The Hubbert peak theory says that for any given geographical area, from an individual oil-producing region to the planet as a whole, the rate of petroleum production tends to follow a bell-shaped curve.It is one of the primary theories on peak oil.. For each of the following functions, find the absolute maximum and absolute minimum over the specified interval and state where those values occur. As an Amazon associate we earn from qualifying purchases. If the slope is decreasing at the turning point, then you have found a maximum of the function. y=(x−x2)2y=(x−x2)2 over [−1,1][−1,1], y=|x+1|+|x−1|y=|x+1|+|x−1| over [−3,2][−3,2], y=sinx+cosxy=sinx+cosx over [0,2π][0,2π], y=4sinθ−3cosθy=4sinθ−3cosθ over [0,2π][0,2π]. Then, solve for them explicitly. To maximize a function means to find its maximum value in a given range of values. A function ff has a local minimum at cc if there exists an open interval II containing cc such that II is contained in the domain of ff and f(c)≤f(x)f(c)≤f(x) for all x∈I.x∈I. The production of gold can be modeled by \(G(t)=\frac{(25t)}{(t^2+16)}\), where t is the number of years since the rush began \((0≤t≤40)\) and \(G\) is ounces of gold produced (in millions). A function may have both an absolute maximum and an absolute minimum, just one extremum, or neither. Here is a set of practice problems to accompany the Functions Section of the Review chapter of the notes for Paul Dawkins Calculus I course at Lamar University. citation tool such as, Authors: Gilbert Strang, Edwin “Jed” Herman. 4. Note:Step 2 at first seems a little strange, but remember that the derivative of a function represents the rate of the increase or decrease of the original function. Suppose ff has a local maximum at c.c. 19 examples: Suppose individuals are held responsible for their preferences to earn or… [T] Graph the function y=eax.y=eax. In the event that there are multiple values for ‘t’, simple trial and error will lead the way to your minima or maxima. Textbook solution for Calculus 2012 Student Edition (by… 4th Edition Ross L. Finney Chapter 5.4 Problem 35E. First, the term absolute here does not refer to absolute value. -20x + 1500 = 0. The production of gold can be modeled by G (t) = (25 t) (t 2 + 16), G (t) = (25 t) (t 2 + 16), where t t is the number of years since the rush began (0 ≤ t ≤ 40) (0 ≤ t ≤ 40) and G G is ounces of gold produced (in millions). All three of these functions are defined over bounded intervals. The extreme value theorem states that a continuous function over a closed, bounded interval has an absolute maximum and an absolute minimum. We have f′(x)=3x2=0f′(x)=3x2=0 when x=0.x=0. Can you have a finite absolute maximum for y=ax2+bx+cy=ax2+bx+c over (−∞,∞)?(−∞,∞)? Therefore, by Fermat’s Theorem, the point cc at which the local extremum occurs must be a critical point. If ff is a continuous function over the closed, bounded interval [a,b],[a,b], then there is a point in [a,b][a,b] at which ff has an absolute maximum over [a,b][a,b] and there is a point in [a,b][a,b] at which ff has an absolute minimum over [a,b].[a,b]. Step 3: Find the corresponding y-coordinates for the x-value (maximum) you found in Step 2 by substituting back into the original function. University Math Calculus Linear Algebra Abstract Algebra Real Analysis Topology Complex Analysis Advanced Statistics Applied Math Number Theory Differential Equations. If you are redistributing all or part of this book in a print format, Let ff be a function defined over an interval II and let c∈I.c∈I. The absolute maximum of ff over II and the absolute minimum of ff over II must occur at endpoints of II or at critical points of ff in I.I. This is a minimum. Getting Ready: Appendix: Precalculus stuff to know cold . Free Maximum Calculator - find the Maximum of a data set step-by-step. S6 Appendix 1. The Derivative In calculus, the key concept is that of the derivative of a function. To carry around a concrete example, I use the function f(x) = x2 x+2. For the following exercises, find the critical points in the domains of the following functions. With this idea in mind, let’s examine a procedure for locating absolute extrema. Applied Calculus for the Managerial, Life, and Social Sciences (8th Edition) Edit edition. Visit http://ilectureonline.com for more math and science lectures!In this video I will find the number of tree=? This efficiency is a goal which can be achieved by improving productivity. There then exists an open interval II such that f(c)≥f(x)f(c)≥f(x) for all x∈I.x∈I. If an absolute extremum for a function ff occurs at an endpoint, we do not consider that to be a local extremum, but instead refer to that as an endpoint extremum. Where R is maximum revenue. It is important to understand the difference between the two types of minimum/maximum (collectively called extrema) values for many of the applications in this chapter and so we use a variety of examples to help with this. © 1999-2020, Rice University. Warning: Finding the minima of a function is fairly straightforward – but beware, in more complex equations, it can be quite difficult to obtain all of the values for ‘t’ where the function equals zero. Prove this formula using calculus. y={x2−4x0≤x≤1x2−411y={x2+1x≤1x2−4x+5x>1. Find the critical points, maxima, and minima for the following piecewise functions. Creative Commons Attribution-NonCommercial-ShareAlike License 4.0 license. managed by competent technicians with an eye single to maximum production of goods and services; instead of, as now, being manhandled by ignorant business men with an eye single to maximum profits; the resulting output of goods and services would doubtless exceed the current output by several hundred per cent. The function in graph (f) is continuous over the half-open interval [0,2),[0,2), but is not defined at x=2,x=2, and therefore is not continuous over a closed, bounded interval. For answering this type of question on the AP calculus exam, be sure to record this figure using the unit of measurement presented in the short-answer problem. More Related Concepts. At x=2,x=2, the derivative f′(x)f′(x) does not exist, since the function ff has a corner there. For profit maximization short-answer problems on the AP Calculus exam, this unit of measurement is almost certainly US dollars or $. Therefore, x=0x=0 is a critical point. The OpenStax name, OpenStax logo, OpenStax book It is important to pick one value greater than and one less than your extrema. This book is Creative Commons Attribution-NonCommercial-ShareAlike License Tip: This information is important in creating accurate graphs. For the extreme value theorem to apply, the function must be continuous over a closed, bounded interval. The formula for calculating the maximum revenue of an object is as follows: R = p*Q. In this example, inserting x = 75 into the profit equation -10x2 + 1500x – 2000 produces -10(75)2 + 1500(75) – 2000 or 54,250 in profit. Suppose ff has a local extremum at cc and ff is differentiable at c.c. Get an answer for 'find the production level that will maximize profit. The function has an absolute maximum over [0,4][0,4] but does not have an absolute minimum. The absolute maximum value of the function occurs at the higher peak, at x=2.x=2. it has an absolute maximum (and an absolute minimum) in that interval. From. Typically, it is proved in a course on real analysis. Calculus Cookbook A1.1. For now, let’s turn our attention to finding critical points. We recommend using a where ‘f(t)’ is the money gained and ‘t’ is time. Rather, it states that critical points are candidates for local extrema. However, x=0x=0 is also a point of interest. Step 2: Check each turning point (at x = 0 and x = -1/3)to find out whether it is a maximum or a minimum. Pick two very close points to the location of our extrema (t = 1/4). From Equation 4.4 we conclude that f′(c)≤0.f′(c)≤0. While the function itself represents the total money gained, the differentiated function gives you the rate at which money is acquired. In other words, local extrema can only occur at critical points. The graph can be described as two mountains with a valley in the middle. If you’ve spent any time at all in the world of mathematics, then you’ve probably seen your fair share of graphs with attached functions. Example problem: Find the local maximum value of y = 4x3 + 2x2 + 1. Videos. However, it is not always easy to see, since the interesting features on the graph of a function may not be visible because they occur at a very small scale. AP Calculus Syllabus: AB, BC. Start today. There are a couple of key points to note about the statement of this theorem. f(t) = 100t2 – 50t + 9, Three sides of the enclosure will be built of redwood fencing, at a cost of $7 per running foot. Trending. Note this theorem does not claim that a function ff must have a local extremum at a critical point. Step 5: Calculate the maximum profit using the number of units produced calculated in the previous step. An absolute extremum may be positive, negative, or zero. x = 75. This has two zeros, which can be found through factoring. However, the function in graph (e) is the only one that has both an absolute maximum and an absolute minimum over its domain. covers, OpenStax CNX name, and OpenStax CNX logo are not subject to the Creative Commons license and may Is it possible to have more than one absolute maximum? Step 3: Set the equation equal to zero: In this section, we’ll discuss how to find these extreme values using calculus. Although the function in graph (d) is defined over the closed interval [0,4],[0,4], the function is discontinuous at x=2.x=2. Forums. For the following exercises, find the local and absolute minima and maxima for the functions over (−∞,∞).(−∞,∞). In this section we define absolute (or global) minimum and maximum values of a function and relative (or local) minimum and maximum values of a function. Step 1: Differentiate your function. In this example, inserting x = 75 into the profit equation -10x 2 + 1500x – 2000 produces -10 (75) 2 + 1500 (75) – 2000 or 54,250 in profit. For example, consider the functions shown in Figure 4.13(d), (e), and (f). Learn more Accept. Assume the graph represents the entirety of each function. Finding the maximum and minimum values of a function also has practical significance because we can use this method to solve optimization problems, such as maximizing profit, minimizing the amount of material used in manufacturing an aluminum can, or finding the maximum height a rocket can reach. Open House Info: AB & BC, Bingo, & Schedule. Tip: You can check your answer by sketching the graph and looking for the highest and lowest points. Menu Maximum production. When p = 100, R (100) = $ 50,000. A function ff has a local extremum at cc if ff has a local maximum at cc or ff has a local minimum at c.c. … Q is the total quantity of goods at maximum demand. f(t) = 100t2 – 50t + 9 is differentiated to become f ‘(t) = 200t – 50. Except where otherwise noted, textbooks on this site Forums Login. However, the following theorem, called the Extreme Value Theorem, guarantees that a continuous function ff over a closed, bounded interval [a,b][a,b] has both an absolute maximum and an absolute minimum. Step 4: Use algebra to find how many units are produced from the equation you wrote in Step 3. Therefore, the absolute maximum occurs at p = $ 100. How many units of cell phone (in thousands) minimizes this cost function? Use a graphical argument to prove your hypothesis. However, f(x)=x3f(x)=x3 is increasing over (−∞,∞),(−∞,∞), and thus ff does not have a local extremum at x=0.x=0. This Calculus 3 video tutorial explains how to find absolute maximum and minimum values given a multivariable function such as f(x,y). © Sep 2, 2020 OpenStax. Finding Maxima and Minima using Derivatives. Describe how to use critical points to locate absolute extrema over a closed interval. For the following exercises, find the local and/or absolute maxima for the functions over the specified domain. Ability to take a photo of your math problem using the app. The Practically Cheating Calculus Handbook, The Practically Cheating Statistics Handbook, Maximizing Profits (Given Profit and Loss Function), How to Find Maximum Profit: Overview of Maximization. Step 1: Differentiate the function, using the power rule. For the following functions, use a calculator to graph the function and to estimate the absolute and local maxima and minima. A function ff has a local maximum at cc if there exists an open interval II containing cc such that II is contained in the domain of ff and f(c)≥f(x)f(c)≥f(x) for all x∈I.x∈I. Find more Mathematics widgets in Wolfram|Alpha. Calculus I or needing a refresher in some of the early topics in calculus. https://study.com/academy/lesson/practical-applications-of-calculus.html Define local extrema. However, since x2+1≥1x2+1≥1 for all real numbers xx and x2+1=1x2+1=1 when x=0,x=0, the function has a smallest value, 1, when x=0.x=0. Similarly, it can be shown that f′(c)≥0.f′(c)≥0. If the function representing this rate is equal to zero, that means the actual function is not increasing or decreasing at that specific point. Are they maxima, minima, or neither? For each of the following functions, find all critical points. Choosing a particular curve determines a point of maximum production based on discovery rates, production rates and cumulative production. 142. Determine the maximum demand of a … However, cc being a critical point is not a sufficient condition for ff to have a local extremum at c.c. Such a value cc is known as a critical point and it is important in finding extreme values for functions. Explain why or why not using graphical arguments. This function has an absolute maximum and an absolute minimum. d/dx (4x3 + 2x2 + 1) = 12x2 + 4x The proof of the extreme value theorem is beyond the scope of this text. To answer this question, let’s look at Figure 4.14 again. Constant terms disappear under differentiation. Example question: Find the profit equation of a business with a revenue function of 2000x – 10x2 and a cost function of 2000 + 500x. Want to cite, share, or modify this book? AP Calculus Survival Guide . The case in which ff has a local minimum at cc can be handled similarly. Where is the slope zero? Explain why or why not using graphical arguments. In these cases, insert all possible answers into the profit equation to calculate their profits and then select the answer that produces the highest profit as the profit maximizing number of units produced. For example, the profit equation -10x2 + 1500x – 2000 becomes -20x + 1500. Here, I’m using the power rule: I’ve tried to make these notes as self contained as possible and so all the information needed to read through them is either from an Algebra or Trig class or contained in other sections of the Calculus, 4th edition Includes index Addeddate 2015-12-16 04:56:26 Foldoutcount 0 Identifier Calculus_4th_edition Identifier-ark ark:/13960/t6xw88w4q Isbn 9780073383118 0073383112 Lccn 2010030314 Ocr ABBYY FineReader 11.0 Openlibrary OL24411588M Openlibrary_edition OL24411588M Openlibrary_work OL15444036W Pages 1232 Ppi 300 Scanner Internet Archive Python library 0.9.1. This function has an absolute maximum at an endpoint of the interval. The Derivative tells us! Where does it flatten out? Therefore, for xx near c,c, but x>c,x>c, we have f(x)−f(c)x−c≤0.f(x)−f(c)x−c≤0. This fact is known as Fermat’s theorem. We say ff has a local maximum at x=0.x=0. Given a particular function, we are often interested in determining the largest and smallest values of the function. Step 3: Test the surrounding values of t (in your original equation) to decide whether your value is a maxima or a minima. Find when the maximum (local and global) gold production occurred, and the amount of gold produced during that maximum. d/dx (12x2 + 4x) = 24x + 4 OpenStax is part of Rice University, which is a 501(c)(3) nonprofit. Later in this chapter, we show how to determine whether a function actually has a local extremum at a critical point. Let ff be a continuous function over a closed, bounded interval I.I. Similarly, the function ff does not have an absolute minimum, but it does have a local minimum at x=1x=1 because f(1)f(1) is less than f(x)f(x) for xx near 1. You have mentioned "output quantity," but you can't be trying to maximize that, since $0\le x\le1600$ tells you that the maximum output quantity is 1600. This function has both an absolute maximum and an absolute minimum. These two graphs illustrate why a function over a bounded interval may fail to have an absolute maximum and/or absolute minimum. Let mm be the number of local minima and MM be the number of local maxima. y=(x−1)a,y=(x−1)a, given that a>1a>1 and a is an integer. If ff has an absolute maximum on II at cc or an absolute minimum on II at c,c, we say ff has an absolute extremum on II at c.c. A ball is thrown into the air and its position is given by h(t)=−4.9t2+60t+5m.h(t)=−4.9t2+60t+5m. Free calculus calculator - calculate limits, integrals, derivatives and series step-by-step Use a graphing utility to determine whether the function has a local extremum at each of the critical points. This idea is useful in determining where absolute extrema occur. We say ff has an absolute maximum on II at cc if f(c)≥f(x)f(c)≥f(x) for all x∈I.x∈I. We say that f(x)=x2+1f(x)=x2+1 does not have an absolute maximum (see the following figure). https://openstax.org/books/calculus-volume-1/pages/1-introduction, https://openstax.org/books/calculus-volume-1/pages/4-3-maxima-and-minima, Creative Commons Attribution 4.0 International License, Using the chain rule, we see the derivative is, By the chain rule, we see that the derivative is, Compare all values found in (1) and (2). (0, 9), (1/4, 2.75), (2,59). ADVERTISEMENTS: The process of optimisation often requires us to determine the maximum or minimum value of a function. If the slope is increasing at the turning point, it is a minimum. Problem Solving > > How to find maximum profit. For example, the revenue equation 2000x – 10x2 and the cost equation 2000 + 500x can be combined as profit = 2000x – 10x2 – (2000 + 500x) or profit = -10x2 + 1500x – 2000. For the following problems, draw graphs of f(x),f(x), which is continuous, over the interval [−4,4][−4,4] with the following properties: Absolute maximum at x=2x=2 and absolute minima at x=±3x=±3, Absolute minimum at x=1x=1 and absolute maximum at x=2x=2, Absolute maximum at x=4,x=4, absolute minimum at x=−1,x=−1, local maximum at x=−2,x=−2, and a critical point that is not a maximum or minimum at x=2x=2, Absolute maxima at x=2x=2 and x=−3,x=−3, local minimum at x=1,x=1, and absolute minimum at x=4x=4. Draw a graph to support your explanation. Consider a continuous function ff defined over the closed interval [a,b].[a,b]. Calculus can help! Our mission is to improve educational access and learning for everyone. The manager of a garden store wants to build a 600 square foot rectangular enclosure on the store’s parking lot in order to display some equipment. If you are examining a function over an interval (a,b),(a,b), for aa and bb finite, is it possible not to have an absolute maximum or absolute minimum? To do this, differentiate a second time and substitute in the x value of each turning point. Therefore, the function does not have a largest value. Therefore, the maximum monthly productivity was found in the 25th month. Given the graph of a function f,f, it is sometimes easy to see where a local maximum or local minimum occurs. For instance, 0 and 1 are great choices, not only because they are very close, but also because they will allow you to do the computation in your head. For example, consider the function f(x)=x3.f(x)=x3. For the following exercises, find the critical points of the following generic functions. 20x = 1500 The given function has an absolute minimum of 1 at, Graphs (a), (b), and (c) show several possibilities for absolute extrema for functions with a domain of. $9.95 per month (cancel anytime). 20x = 1500. x = 75. Explain how to find the critical points of a function over a closed interval. Therefore. Is it possible to have no absolute minimum or maximum for a function? This fact is supported by the fact that the data points immediately to the left and the right of this value are both higher. This function has a local maximum and a local minimum. both Maximums and Minimums , the direct effects must outweigh the cross effects Rules for two variable Maximums and Minimums 1. Therefore, f′(c)=0.f′(c)=0. This is a maximum. Typically, it is wise to pick quick and easy values for this part of the procedure. The total cost for labor and capital cannot exceed $240,000. It takes into account the input and output of different factors, which are obvious from the inputs required by our productivity calculator.One of the core purposes of every business organization is to produce more goods or services, while using less resources. Maximum f xx < 0 f yy < 0 f yyf xx −f xyf yx > 0 2. Imagine a function f that associates to every number x another number f(x), in the way that functions do. Find the absolute maximum and absolute minimum of f(x)=x2−4x+3f(x)=x2−4x+3 over the interval [1,4].[1,4]. It occurs at x=0,x=0, as shown in Figure 4.13(b). At this point, we know how to locate absolute extrema for continuous functions over closed intervals. For the following exercises, consider the production of gold during the California gold rush (1848–1888). Draw a graph that supports your hypothesis. With calculus, you can find the derivative of the function to find points where the gradient (slope) is zero, but these could be either maxima or minima. Get the free "Max/Min Finder" widget for your website, blog, Wordpress, Blogger, or iGoogle. The extreme value theorem cannot be applied to the functions in graphs (d) and (f) because neither of these functions is continuous over a closed, bounded interval. Finding that minimum value is how to find minimum profit. Step 2: Set the equation equal to zero and solve for t. 0 = 200t – 50 Breakdown of the steps and substeps to each solution. We have also defined local extrema and determined that if a function ff has a local extremum at a point c,c, then cc must be a critical point of f.f. Math Discussions Math Software Math Books Physics Chemistry Computer Science Business & Economics Art & Culture Academic & Career Guidance. Step 2: Find the derivative of the profit equation (here’s a list of common derivatives). You should be able to quickly draw a rough sketch of what this looks like – what you’ll find is that there is a minimum at 1/4. A company that produces cell phones has a cost function of C=x2−1200x+36,400,C=x2−1200x+36,400, where CC is cost in dollars and xx is number of cell phones produced (in thousands). We have step-by-step solutions for your textbooks written by Bartleby experts! If the interval II is open or the function has even one point of discontinuity, the function may not have an absolute maximum or absolute minimum over I.I. The quotient rule states that the derivative of f(x) is fʼ(x)=(gʼ(x)h(x)-g(x)hʼ(x))/[h(x)]². Integral. If so, construct such a function. → 50 = 200t, Spleen: Prerequisite Algebra Skills (WS/KEY) Chapter P: Calculus Prerequisites for all real numbers x,x, we say ff has an absolute maximum over (−∞,∞)(−∞,∞) at x=0.x=0. This was his way of dispensing with friction. 12x2 + 4x = 4x(3x+1), which equals zero when x = 0 or x = -1/3. Learning Objectives . Find when the minimum (local and global) gold production occurred. This will be useful in the next step. Find all critical points for f(x)=x3−12x2−2x+1.f(x)=x3−12x2−2x+1. When you are checking for critical points, explain why you also need to determine points where f'(x)f'(x) is undefined. Step 1: The first step is to differentiate the function with respect to t: -2t^2 ==> -4t, 100t ==> 100, and 180 ==>0; This gives M' (t)=-4t + 100. Can you have a finite absolute maximum for y=ax3+bx2+cx+dy=ax3+bx2+cx+d over (−∞,∞)(−∞,∞) assuming a is non-zero? [T] y=12x5+45x4+20x3−90x2−120x+3y=12x5+45x4+20x3−90x2−120x+3, [T] y=x3+6x2−x−30x−2y=x3+6x2−x−30x−2.
