The video tutorial explains the rational zero test, which helps identify possible rational zeros of a polynomial. It covers finding factors of P and Q, listing and simplifying P/Q, and applying the test using graphing calculators and synthetic division. The technique is useful for determining potential rational zeros, although it doesn't guarantee the exact zero.
