9.5 – Radical Equations

 

Radical Equations:     An equation with a radical.

 

            To Solve:

1.)    Isolate the radical on one side of the equation.

 

2.)    Raise both sides of the equation to the inverse power of the radical.

 

3.)    Simplify each side.  If a radical still remains, repeat steps 1 and 2.

If no radicals remain, solve the equation.

 

4.)    Check for extraneous roots!
