8-112.

Carlo is trying to factor the polynomial** ** to determine all of its zeros. He discovers one factor by making a guess and dividing the polynomial, so he has

*. Now he is trying to factor*

*, so he tries dividing it by*

*“You should look at the graph.”*

How does the graph help?

It shows that

is a double root, sois a repeated factor. Complete the problem.
