You can put this solution on YOUR website! Without any computation, x = 1 *has* to be the only real solution because the functions x^2 and sqrt(x) are strictly increasing when x >= 0 (note: if x < 0, then the LHS is non-real). Because x = 1 is a solution, it must be the only real solution.
Assuming complex-valued square roots, you can solve by isolating sqrt(x) and squaring:
