If a conic $ax^2+by^2+2hxy+2gx+2fy+c=0$ and say:

How to find the eccentricity and the semi-axes of this conic. I do understand that if its a hyperbola only one of the semi axes will be real.

hey thanks but I am not exactly sure, how it fits with the answer. The link talks about the equation in light of rotated axes, whereas I was looking more for eccentricity – Soham Sep 11 '12 at 16:41
