9-115.

Use your answers to the previous problem to complete each part below. Homework Help ✎

Factor

*x*^{3}– 5*x*^{2}+ 11*x*– 15.Determine the roots of

*P*(*x*) =*x*^{3}– 5*x*^{2}+ 11*x*– 15.

There are 2 factors. (*x* − 3) is one factor. Use long division to find the other factor.

Once the polynomial is factored, use the Zero Product Property to solve.

This is a 3^{rd} degree polynomial function, so find 3 answers. One of the answers is *x* = 1 + 2* i*.
