Solving a Radical Equation by Squaring Both Sides

The video tutorial explains how to solve equations involving radicals by squaring both sides to eliminate the radical, forming a quadratic equation. It covers solving the quadratic equation using factoring and the zero product property. The tutorial emphasizes the importance of checking for extraneous solutions by substituting the solutions back into the original equation to verify their validity.

Define extraneous solutions and provide an example from the text.

How do you verify if a solution is valid for the original equation?
