Learn to find all of the possible rational zeros by using p over q

The video tutorial explains how to determine all possible rational zeros of a polynomial using the rational zero test. It introduces the concepts of P and Q, where P is the constant term and Q is the leading coefficient. The tutorial details how to calculate the factors of P and Q, and how to use these factors to find all possible rational zeros by considering the plus or minus of P divided by Q. The importance of understanding rational numbers and their role in identifying zeros is emphasized, and common questions about the process are addressed.

Why is it important to only include unique rational zeros in the final list?

Can the number 3 be a rational zero based on the factors discussed? Explain your reasoning.
