10-122.

Using your answers to the previous problem: Homework Help ✎

Factor

*f*(*x*) =*x*^{3}− 5*x*^{2}+ 11*x*− 15.Solve

*f*(*x*) = 0.

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*.
