Question

Help me to answer a) and solve the problem in detail, thank you.

Answer 1

We have the next polynomial

$2x^3+7x^2-8x+3$

In order to find the remainder when we divide the polynomial above by x+1. Using the remainder theorem we will evaluate x=-1

$P(-1)=2(-1)^3+7(-1)^2-8(-1)+3=16$

The remainder is 16

ANSWER

The remainder of the given polynomial is 16.
