Answer:

D) 2x^2 + 11x^3 + 12x^2 - 10x - 8

Step-by-step explanation:

you multiply each term of the first expression with each term of the second expression and add all the terms

so start with x^2 * 2x^2 = 2x^4

x^2 * 3x = 3x^3

x^2 * -4 = -4x^2

4x * 2x^2 = 8x^3

at this point it's clear that the correct answer is D but we can continue

4x * 3x = 12x^2

4x * -4 = -16x

4x^2

6x

-8

by adding

2x^2 + 11x^3 + 12x^2 - 10x - 8
