Question

g(x) = x3 + 2x2 - x - 2 to answer all the questions in Part II. 1. Use synthetic division to show that x = -2 is a zero of the polynomial.

Answer 1

Answer:$x^{2} -1$

Step-by-step explanation:

Given :$g(x)=x^{3} +2x^{2} -x-2$

Factor x+2,x=-2

Using synthesis division:

-2 )  1 2   -1  -2

        -2    0   2

      1  0   -1   0

$x^{2} +0x-1$
