EQUATIONS CONTAINING VARIABLES UNDER ONE OR MORE RADICALS

**
Recall the following:
**

**In order to solve for***x*, you must isolate*x*.**In order to isolate***x*, you must remove it from under the radical.**If there are two radicals in the equation, isolate one of the radicals.****Then raise both sides of the equation to a power equal to the index of the isolated radical.****Isolate the remaining radical****Raise both sides of the equation to a power equal to the index of the isolated radical.****You should now have a polynomial equation. Solve it.****Remember that you did not start out with a polynomial; therefore, there may be extraneous solutions. Therefore, you must check your answers.**
