Space to start then enter the Quadratic, Linear, then Constant coefficients, and this will give you the answer/s to the equation.
Thanks to @wmacfarl and my dad for all the support in this. Log: 12/27/2016: Fixed some presentation bugs with radicals. 12/23/2016: Fixed most presentation bugs with imaginary numbers. There are still presentation bugs with radicals that are waiting to be ironed out. 12/20/2016: Added imaginary number (negative discriminant) support. There are still some presentation bugs, but those will (hopefully) be out by 12/21/2016. 12/17/2016: Those bugs have been fixed. This program (hopefully) will answer all quadratics with real roots, and will alert you if it can't solve the quadratic because of negative discriminant. 12/15/2016: Shared. There are still some bugs in the program, so beware, and don't use this for your math test.
