Consider the polynomials given below, P(x) = x^4 + 3x^3 +2x^2 -x+2
Q(x) = (x^3 + 2x^2 + 3) (x^2 -2)
Determine the operation that results in the simplified expression below.
x^5 + x^4 -5x^3 -3x^2 + x-8

Q-P

Step-by-step explanation:Q in standard form is x^5+2x^4-2x^3-x^2-6 and if you subtract P (x^4+3x^3+2x^2-x+2) you get x^5+x^4-5x^3-3x^2+x-8

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

-2 is the right
