Radical Equation with a Extraneous Solution

The video tutorial explains how to solve radical equations and identify extraneous solutions. It begins by introducing the concept of radical equations and the potential for extraneous solutions. The instructor then demonstrates how to isolate the square root in an equation and explains the process of squaring both sides, which can lead to extraneous solutions. The tutorial continues with solving the resulting quadratic equation and emphasizes the importance of checking solutions to identify any that are extraneous. The video concludes with a brief mention of future content involving square roots on both sides of an equation.
