Solving radical equations

Radical equations are equations that have variables stunk inside a radical. We will show you how to solve this type of equations in this lesson.


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,
