Identifying Extraneous Solutions in Radical Equations

The video tutorial explains how to identify extraneous solutions in radical equations. It emphasizes the importance of ensuring that solutions do not result in negative numbers under a square root, as this would be undefined. The concept of radicands is introduced, and the process of solving radical equations is demonstrated, including squaring both sides and factoring. The tutorial concludes with checking solutions through substitution to confirm their validity.
