12. Use the remainder theorem to find P (-2) for P(x) =x^3+2x^2-x-7. Specifically, give the quotient and the remainder for the associated division and the value of P (-2).

Question

Quotient =? Remainder =? P (-2) =?

Answer 1

P(-2) is the remainder when P(x) is divided by (x+2)

P(-2) = -5, so

P(x) = (x+2)(x^2-1) - 5

Answer 2

Find quotient and remainder using long division
P(x)=X^2-6x-8 ,d(x)=-4
