let equation of an ellipse be x^2+4y^2+6x8y+9=0
a. Find the standard form of the ellipse
b. Find the center
c. Find the vertices
d. Find the foci
e. Find the eccentricity

Steve
x^2+4y^2+6x8y+9=0
x^2+6x + 4y^28y = 9
x^2+6x+9 + 4y^28y+4 = 9+9+4
(x+3)^2 + 4(y1)^2 = 4
(x+3)^2/4 + (y1)^1 = 1
Now the rest should be easy. Come on back if you get stuck.
