Solving Radical Equations Concepts

This video tutorial explains how to solve radical equations with two radicals. It outlines the steps to isolate radicals, raise both sides to the power of the index, and solve the equation. The video includes two examples, demonstrating the process and highlighting potential extraneous solutions. It emphasizes the importance of checking solutions to ensure accuracy.

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

• Isolate the variable

• Combine both radicals on one side

• Put one radical on each side of the equal sign

• Square each term individually

What should you do if one radical remains after the initial squaring?

• Divide both sides by the index

• Add a constant to both sides

• Ignore the remaining radical

• Isolate the remaining radical and square again
