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.
