If c (x) = 4x - 2 and d (x) = x2 + 5x, what is (cd) (x)

c (x) = 4x - 2

d (x) = x^2 + 5x

4x - 2 (x^2 + 5x)

Using FOIL, distribute each term appropriately.

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

Combine like terms.

4x^3 + 18x^2 - 10x is the simplified polynomials achieved when c (x) and d (x) are multiplied.
