Solving Radical Equations Concepts

The video tutorial explains how to solve a radical equation with two radicals. It outlines the process of isolating radicals on each side, squaring both sides, simplifying, and solving the resulting equation. The solution is verified by substituting it back into the original equation. The example demonstrates that the solution x = 25 is correct, and the video concludes with a promise of another example in the next video.

What is the first step in solving a radical equation with two radicals?

• Divide both sides by a radical

• Isolate one radical on each side
