This algebra 2 math tutorial from NutshellMath offers help solving equations containing radicals. Radicals are used in many realms of mathematics, and it is important to know how to effectively solve equations containing radicals.
In order to deal with a radical in an algebraic equation, the first step is to isolate the radical on one side of the equation. If the equation has two radicals, isolate only one first. By raising both sides to the same power, it is possible to eliminate the isolated radical. Next, use algebra to solve for the remaining variable. If there is a second radical, it may be necessary to isolate it next and raise both sides to the same power once again. Once a solution has been found, it is a good idea to verify the solution(s) is true by plugging the value in for the variable in the initial equation. This will rule out any extraneous solutions that on occasion result from problems with multiple radicals.
