Question

Use the remainder theorem to find P(-2) for P(x)=-2x^4-2x^3+5x^2-3

Answer 1

P' (x) = -8x³ -6x² +10x

Explanation:

Answer 2

1

Explanation:

When using the remainder theorem, all you do is plug in -2.

P(-2) = -2(-2)^4-2(-2)^3+5(-2)^2-3

= -2(16) - 2(-8) + 5(4) - 3

= -32 + 16 + 20 - 3

= 1
