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.

Divide

by**2 by 3 rectangle, labeled as follows: left edge, x, minus 3, top edge, left, x, squared, interior top, left, x squared.****Labels added: Interior bottom, left, negative 3, x, squared, interior top, middle, 2, x squared.****Labels added: top edge, middle, 2, x, interior bottom, middle, negative 6, x, interior top, right, negative x.****Labels added: top edge, right, negative 1, interior bottom, right, 3.**Now use the Quadratic Formula to solve for
