(Medals)

Answer 1

2. The correct answer among the choices provided is 8x6 + 6x5 + 2x4.

Answer 2

1. 8x^6 + 6x^5 + 2x^4

2. 8x^3 - 28x^2 + 4x - 6x^2 + 21x - 3 = 8x^3 - 34x^2 + 25x - 3

3. 2x^4 + 4x^3 + 24x + x^3 + 4x^2 + 24x - 6x^2 - 3x - 18 = 2x^4 + 5x^3 - 2x^2 + 45x - 18

4. 2x^2 + 10x - 4x - 20 = 2x^2 - 14x - 20

5. Distributive: x • x - 3 • x - 2 • x + (-2)(-3) = x^2 - 3x - 2x + 6 = x^2 - 5x + 6

so the answer is 8x6 + 6x5 + 2x4.
