Here's the question you clicked on:

Specify, design and implement a class that can tore information about a quadratic expression. The constructor should set all three coefficients to zero, and another method should allow you to change these coefficients.
http://ideone.com/wI0HZ it's very flawed, but that's the idea of doing it. Btw the repr function was just to display the actual polynomial and is not really necessary
Better to have a more flexible Polynomial class, with fields such as the degree etc, and the repr function, and then have a Quadratic class inherit from that class.
Sorry for the late response, I needed it in Java.
:( I don't really know C++ or Java so well
