Exercise 61 Page 79

First determine the x-intercepts of the polynomial.

C

Practice makes perfect

Let's first determine the x-intercepts of the polynomial.

The graph of the polynomial crosses the x-axis at (-2,0), (-1,0), and (2,0). With this, we can write three factors for the polynomial. x+2, x+1, x-2 Therefore, x-1 is not a factor of the polynomial. The correct option is C.
