The video tutorial explains how to determine possible rational zeros of a polynomial using the rational zero test. It covers the process of listing potential zeros as P/Q, where P is the factors of the constant term and Q is the factors of the leading coefficient. The tutorial then discusses methods to verify which of these potential zeros are actual zeros, using graphing technology, synthetic division, and the remainder theorem. Finally, it demonstrates the verification process with an example, confirming the zeros and concluding the lesson.
