Conics:   circle, ellipse, parabola and hyperbola

How to tell the difference:

circle:  two quadratic terms, same sign, same coefficient

ellipse:  two quadratic terms, same sign different coefficients

parabola:  only one quadratic term

hyperbola:  two quadratic terms, different signs!

Practice:  NAME THAT CONIC SECTION!

**Quadratics must be on the same side of the = sign
