Question

Find (f•g)(x).

f(x) = x^2 + 4x
g(x) = 6x
Write your answer as a polynomial in simplest form.

Answer 1

6x^3 + 24x^2

Explanation:

We need to find (f * g)(x)

If we distribute the "x" here, we should get f(x) * g(x), which is what we have to solve for

f(x) * g(x) = 6x(x^2 + 4x)

= 6x^3 + 6x(4x)

= 6x^3 + 24x^2

This is the simplest expression you can get
