Learn how to apply rational zero test to determine the number of possible rational zeros

The video tutorial covers the concept of rational and irrational numbers, explaining that rational numbers can be expressed as fractions. It introduces the rational zero test, which helps identify potential zeros of a polynomial by using synthetic division. The process involves labeling constants and coefficients as P and Q, then calculating possible zeros by dividing factors of P by factors of Q. The tutorial demonstrates how to simplify these fractions to find potential zeros, providing a step-by-step guide to applying the rational zero test effectively.
