EQUATIONS CONTAINING VARIABLES UNDER ONE OR MORE RADICALS
- In order to solve for x, you must isolate x.
- In order to isolate x, you must remove it from under the radial.
- If there are two radicals in the equation,isolate one of the radicals.
- Then raise both sides of the equation to a power equal to the index
of the isolated radical.
- Isolate the remaining radical.
- Raise both sides of the equation to a power equal to the index of the
- You should now have a polynomial equation. Solve it.
- Remember that you did not start out with a polynomial; therefore,
there may be extraneous solutions. Therefore, you must check your answers.
