Question

What is the remainder R when the polynomial p(x) is divided by (x -1)?

P(x) = 2x3 + x2 - 2x - 1

Answer 1

The answer to this question is

-6

Answer 2

The remainder is 0

Explanation:

Using the remainder theorem,plug in the zeros of the factor into the polynomial.

The zeros of the factor—›x-1=0,x=1

Plugging 1 into the polynomial

P(1)=2(1)³+(1)²-2(1)-1=0
