Question

Which expression is equal to f(x) · g(x)? f(x)=4x^2+3x and g(x)= -4x-6. PLEASE HELP

Answer 1

-16x³ - 36x² - 18x

Explanation:

So here we just need to multiply these two functions together

f(x)*g(x) = (4x² + 3x)(-4x - 6)

Our first step is to foil: (4x²)(-4x) + (4x²)(-6) + (3x)(-4x) + (3x)(-6)

Then we can simplify each term by multiplying : -16x³ - 24x² - 12x² - 18x

We can than combine any like terms: -16x³ - 36x² - 18x
