A friend of mine had written a program that would balance chemical equations. I didn't want to copy her, nor did I think I'd be able to write such a program so I decided to start with a simple quadratic equation solver.

I just wish I had done this before solving 100s of them as homework.

Right now, it can only solve them using the factorisation (or splitting the middle term) method. But, other methods will be added soon. Here's a demo.
