11. From 1990 to 1996, the number of students S enrolled in college can be modeled by S = 134.56x 2 – 1417x + 26,628. And, the average number of units U carried is modeled by U = 0.25x + 15, where x is the number of years since 1990. Write a model for the total number of units T carried by students x years after 1990. 6.3 Adding, Subtracting, and Multiplying Polynomials, p. 338 Objective: To Add, Subtract, and Multiply Polynomials; CA Std. 3.0 The total number of credits carried by students is the number of students multiplied by the average number of units. Or, T = S × U Which is, T = (134.56x 2 – 1417x + 26,628) × (0.25x + 15) In this lesson, you will learn how to add, subtract, and multiply polynomials.
