Best ResponseYou've already chosen the best response.1Move the roots to one side and the numbers to the other side. Square both sides and simplify. Move the root to one side alone, and everything else to the other side. Square both sides and simplify again. When you find a solution for x, check it in the original equation because squaring both sides of an equation can introduce extraneous solutions. Extraneous solutions are solutions to the squared equation that are not solutions to the original equation.

Best ResponseYou've already chosen the best response.1Ok. It turns out that by squaring only once, we got rid of the square root of the variable. Now we need to check the solution in the original equation.
