Solving a Radical Equation When You Have One Extraneous Solution

The video tutorial guides students through solving a radical equation. It begins with isolating the radical expression and proceeds to square both sides to eliminate the square root. The instructor explains how to expand the binomial and form a perfect square trinomial. The equation is then set to zero, and solutions are found using factoring. The importance of checking solutions for extraneous results is emphasized, with examples provided to illustrate the process.
