Drag each tile to the correct box. not all tiles will be used. arrange the steps to solve the equation . simplify to obtain the final radical term on one side of the equation. raise both sides of the equation to the power of 2. apply the zero product rule. use the quadratic formula to find the values of x. simplify to get a quadratic equation. raise both sides of the equation to the power of 2 again.
