There are basicly two ways you can work this problem.

The first method is to use a graphing calculator, find one of the rational zeros, if there is one, then calculate the remaining zeros by factoring or using the quadratic formula.

However, if you are not allowed to use a graphing calculator, you can use the rational roots theorem, which is a time-consuming process. I will be using the former process.
 

This particular function has no rational zeros
