The video tutorial introduces the Rational Root Theorem, explaining its significance in solving polynomials, especially higher-order ones. It distinguishes between rational and irrational numbers, providing examples of each. The tutorial then demonstrates how to apply the theorem to find rational roots of polynomials, using a detailed example problem to illustrate the process. The lesson concludes with a summary and encouragement for further practice.
