Question

What is the remainder when q(x)= 2x³ – x² + x - 1 is divided by x+2?

• A. 35
• B. -32
• C. -23
• D. 20

Answer 1

The correct option is C

-23

The remainder theorem tells us that if a polynomial p(x) is divided by x-a then the remainder is equal to p(a).

So, here the remainder

=q(-2)=-16-4-2-1=-23
