Circle: 
and 
terms have equal coefficients.
Ellipse: and terms have same sign but unequal coefficients.
Hyperbola: and terms have opposite sign coefficients.
Parabola: Missing or term (but NOT both)
BTW, ^ does NOT mean "squared"; it means "raised to the power of" and an exponent following the ^ is expected.
