The rational zero theorem tells us the possible rational zeros of a polynomial. So using this theorem, you'll be able to create a list of numbers that might be zeros, but don't have to be. Leading coefficient is very important in this theorem. You'll learn about the cases where the leading coefficient is 1, and cases where it's different from 1. You need to use synthetic substitution to test each possible rational root in your list. The examples in this lesson will help you learn how to find all zeros of the polynomial function.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
