Question

Find the product: -4x (-7x^3 + 4 x 2 + 8x – 6)

Answer 1

-4x (-7x^3 + 4 x 2 + 8x – 6)
Okay, you take the -4x and multiply it by everything in there, so we'll start with the -7x^3:
-4x * -7x^3 = 28x^4 (negative times a negative is a positive and when multiplying like exponents, you add the exponents so x * x^3 = x^4

Now, how do you do -4x * 4?

Answer 2

-16x
