CPM Homework Help : CCA2 Problem 10-122

Using your answers to the previous problem:

Factor $f(x) = x^3 - 5x^2 + 11x - 15$ .
Hint (a):
There are $2$ factors. $(x - 3)$ is one factor. Use long division to find the other factor.

Solve $f(x) = 0$ .
Hint (b):
Once the polynomial is factored, use the Zero Product Property to solve.
More Help (b):
This is a $3$ ^rd degree polynomial function, so find $3$ answers. One of the answers is $x = 1 + 2i$ .
