A conic section has the equation x^2-6x-y^2+4y-4=0. Which one of the following is true?
-------
Complete the square on the x-terms and on the y-terms:
x^2-6x+? - (y^2-4y + ?) = -4
---
x^2 -6x + 9 - (y^2-4y+4) = -4+9-4
Factor:
(x-3)^2 - (y-2)^2 = 1
--------------------------------------
Ans: The equation is a hyperbola with center at (3,2)
