Question 684686: Classify the conic section and write its equation in standard form.
1) 4x^2 + y^2 - 8x - 8 = 0

2) 4x^2 - 25y^2 - 100y = 0
Write the standard equation of the Ellipse. Find the center, vertices, co-vertices and foci.
3)x^2 + 4y^2 - 18x -8y + 81 = 0
Foci:
Vertices:

(1) HYPERBOLE
CENTER=(1,0)
VERTICES=(1-√3,0)
FOCI=(1-√15,0)
Y=2X-2
(2)FOCI=(0,-2-√29
VERTICE=(0,4)(0,0)
CENTER=(0,2)
(3)HYPERBOLA
CENTER(9,-1)
VERTICE=(-1,11)(-1,7)
CO-VERTICE=(9,2)(9,0)
FOCI=(9,-1-√5)
