Can You Solve It? – Square Root Equation

In this math video I (Susanne) explain how to solve a square root equation, why squaring both sides can sometimes lead to a result that isn’t actually a valid solution, and how to check your answer correctly. I also explain the difference between evaluating a square root and solving a quadratic equation, including why one has only one value while the other can have two solutions.
