The video tutorial explains the rational zero test, which helps identify possible rational zeros of a polynomial. It begins by ensuring the polynomial is in standard form and identifying the constant (P) and leading coefficient (Q). The test involves finding factors of P and Q, then creating combinations of these factors to determine potential rational zeros. The tutorial emphasizes simplifying these combinations and removing duplicates. The process is demonstrated step-by-step, with a focus on understanding the method rather than memorizing results.
