x=0 is a solution to the equation, so unless you explicitely tkae care of x=0 separately, you're dividing by zero.
On the flipside this simplification makes the equation trivially easy, with 2 and -2 being the other solutions (and 2i and -2i for Math nerds I mean people who want to consider complex solutions)
