Exploring Radical Equations

This video tutorial teaches how to solve radical equations through a series of examples. It begins with isolating a radical and squaring both sides of the equation. The tutorial covers different scenarios, including equations with non-isolated radicals, quadratic equations, and equations with two radicals. Each example emphasizes the importance of checking solutions to ensure accuracy. The video concludes with a recap of the methods and the significance of verifying solutions.

What is the first step in solving a radical equation?

• Multiply both sides by the radical

• Check the solution

• Isolate one radical on one side

• Square both sides immediately
