X^2 + 7y^2 -12x - 13 = 0 ellipse, circle, hyperbola, parabola??
http://www.wolframalpha.com/input/?i=x%5E2+%2B+7y%5E2+-12x+-+13+%3D+0
know it is an ellipse because of \(x^2+7y^2\) if it was a hyperbola it would be \(ax^2-by^2\)
It's the third time you ask something like this, you should try to understand the concepts.
hyperbola
wait no its not a hyperbola
