Solving Challenging Radical Equations

The video tutorial explains how to solve radical equations with two radicals. It covers isolating one radical, squaring both sides to eliminate it, and then repeating the process for the second radical. The tutorial demonstrates using the distributive property and FOIL method to simplify expressions. It emphasizes the importance of checking solutions to avoid extraneous roots. The video concludes with a reminder to verify solutions and offers additional resources for further learning.

What is the first step in solving equations with two radicals?

• Isolate one radical and square both sides

• Multiply both sides by the least common denominator

• Square both sides of the equation

• Isolate both radicals simultaneously
