The video tutorial explains how to determine possible rational zeros of a polynomial function. It covers the concept of rational zeros, represented as P/Q, where P is the constant term and Q is the leading coefficient. The tutorial details how to find all possible rational zeros by considering the factors of P and Q, and then simplifying these possibilities. It also discusses the application of these rational zeros in finding actual zeros of the polynomial, using methods like graphing and synthetic division.
