Dude x being the root of a quadratic expression two values are expected in your case you took only + when it is +\-. As an expample consider x^2+x-6=0. By your formula roots become complex when they are 2&-3.

Dude your formula does not hold good for all quadratic expressions. Instead use x= -b+(b^2-4ac)^1/2 or x= -b-(b^2-4ac)^1/2
