Question

If c(x) = 4x-2 and d(x) = x^2 + 5x, what is (c•d(x)?

Answer 1

(c•d)(x) = 4x^3 + 18x^2 - 10x

Explanation:

This is the multiplication of two binomials, using the Distributive Property of Multiplication.

(c•d)(x) = (4x - 2)*(x^2 + 5x)

= 4x^3 + 20x^2 - 2x^2 - 10x)

(c•d)(x) = 4x^3 + 18x^2 - 10x
