Answer:
-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
