{{ printedBook.courseTrack.name }} {{ printedBook.name }} Solving a radical equation usually involves three main steps.

- Isolate the radical on one side of the equation.
- Raise each side of the equation to a power equal to the index of the radical to eliminate the radical.
- Solve the resulting equation.
- Check the results for extraneous solutions.
