In order to solve equations where a radical equals a constant, you first need to isolate the square root. From there, square both sides to "undo" the root, and solve for x. Once you have a solution(s), you'll need to check to make sure they're not extraneous. Any value of x that would make the radicand, or whatever is under the radical sign negative is outside of the domain, or extraneous. Here we'll see an example of a radical equation that has no solution.
