3-step approach for solving radical equations:
1) Isolate the "square root" term.
2) i. Square both sides of the equation to get rid of the "square root".
ii. (optional) If the resulting equation still has a "square root" term, repeat steps 1 and 2.
3) Solve the equation, and REMEMBER to substitute answers back into the original equation to identify any EXTRANEOUS ROOTS,
