Put the squared variables on the same side of the equation, then look at the coefficients.


If there is only one squared variable, then parabola.


If the coefficients are equal, then circle.


If the coefficients are unequal but the same sign, then ellipse.


If the coefficients are opposite signs, then hyperbola.
