JavaFX 2 Presents the Quadratic Formula

I recently needed to check some homework answers related to use of the quadratic formula.

It is easy to think that letting users change all aspects of an app UI makes the UI better. We've all heard the "if they don't like it they can change it" argument. It is also very easy to come up with theoretical scenarios where users would actually want to change any one aspects of the UI.
