When you are asked to solve an equation involving a square root, your first goal is to get the radical all by itself, or isolated. You will need to "un-do" whatever is being done to the radical by using the opposite operation. After the radical has been isolated, square both sides of the equation to un-do the root, solve for x, and then check to make sure your solution makes sense by substituting it back into the original equation.
