Choose the STEPS that are NOT involved with solving RADICAL equations.

• Isolate the radical on one side or both sides of the equation.

• Square all problems involving radicals.

• Square root problem? Square BOTH sides to rid the radical.

• Always take the reciprocal of the square root first before solving.

• Check for EXTRANEOUS roots/solutions.
