Procedure

 Solving Radical Equations 1. Isolate the radical (or one of the radicals). 2. Exponentiate to eliminate the isolated radical. 3. Repeat steps 1 and 2 if there are still radicals. 4. Solve the resulting equation. 5. Check your answers using the original equation.

Example 1 Solve for x.

Solution

Isolate
Exponentiate
