Then the conditions of the coefficients in the equation could identify which type of conics the equation represents...

Circle: A=C

Ellipse: A does not=C and AC>0

Hyperbola: AC<0 and if the coefficients have opposite signs

Parabola: A=0 OR C=0

The thing that I do not understand is why... I was wondering if anyone knows a way to explain the reasons to me?
