The equation of a
circle is:
(x - h)² + (y - k)² = r²
The equation of a
parabola is:
(x - h)² = 4p(y - k)
The equation of an
ellipse is:

where variables a and b and the two different measurements of the vertices
The equation of a
hyperbola is:

if it is with a horizontal transverse axis

if it is with a vertical transverse axis
Notice these have a subtraction operation, the exact opposite ellipse.
