If an equation has multiple square roots, we need to get one on each side of the equals sign and then square both sides of the equation to "un-do" the square roots. After solving for x, make sure to go back and check your solution(s) in BOTH original radicals to make sure you would not be taking the square root of a negative number. Such a solution would be called an "extraneous solution."
