General form
Ax2 + Bxy + Cy2 + Dx + Ey+ F = 0.
A, B, C, D, E, F are coefficients
I.
x2 + y2 + 10x – 6y + 18 = 0
How to Put Equations in Standard Form
1. Move constants over to the other side of the equation
(if a parabola, move the variable that isn’t squared over
too)
2. Group all the x’s together and all the y’s together with
parenthesis
3. Factor out anything that’s in front of the x2 or y2.
4. Complete the square for each. Make sure whatever you
add on the left side of the equation, you add on the
right side. (for parabolas, you only complete the square
for the squared variable)
5. (for ellipses and hyperbolas only!) Divide both sides of
the equation by the constant so that what’s left on the
right side is 1.
