Solving Radical Equation by Squaring Both Sides and Checking Answers

The video tutorial explains the process of solving equations involving square roots. It emphasizes the importance of isolating the square root before squaring both sides of the equation. The tutorial draws parallels with solving quadratic equations, where terms must be isolated before taking the square root. An example problem is solved step-by-step, demonstrating the process of undoing square roots by squaring and verifying the solution by plugging it back into the original equation.
