If you only have one squared variable, then you have a parabola.

If the coefficients on the squared variables are equal, then you have a circle.

If the coefficients on the squared variables are different values but the same sign, then you have an ellipse.

If the coefficients on the squared variables have different signs, then you have a hyperbola.
