Find the center, vertices, and foci of the ellipse?
16x^2 + 4y^2 + 64x + -24y + 36 = 0
I managed to find the center and the vertices, but i dont know how to find the foci.
Is there a way to find it by just looking at the equation? or do i have to use a formula?
also, usually ellipse equations are =1 but this one is = -23/64
did i do something wrong...
also please show your work so that i can understand what you did, because i already have the answers, and my answers match them....
ANSWERS: foci: (-2, 3 (plus/minus) 2(sqrt(2))
THANK YOU !!! :D
