Solving Radical Equations and Factors

The video tutorial explains how to solve complex radical equations involving square roots. It begins with an introduction to the topic, followed by a step-by-step solution of two example problems. The first example demonstrates solving a radical equation by squaring both sides, factoring, and checking for extraneous solutions. The second example follows a similar approach but with a different equation. The video concludes with a summary and additional resources for further learning.

What is the first step in solving a complex radical equation with square roots?
