Solving Radical Equations Concepts

The video tutorial explains how to solve equations involving radicals, specifically square roots. The process involves isolating the radical, squaring both sides to eliminate it, and then simplifying the resulting quadratic equation. The quadratic is factored to find potential solutions, which are then checked against the original equation to identify any extraneous solutions. The tutorial emphasizes the importance of verifying solutions when dealing with radicals.

What is the first step in solving an equation with a square root?
