Question
Find an equation of the ellipse with its center at the origin.
center(0,0)
foci(2,0)(-2,0)
major axis=8
My answer is x^2/16 + y^2/15 = 1. Is this correct?

Answers
Reiny
major axis = 8, so a = 8
foci (2,0), so c = 2
b^2 + c^2 = a^2
b^2 + 4 = 64
b^2 = 60
x^2/64 + y^2/60 = 1
foci (2,0), so c = 2
b^2 + c^2 = a^2
b^2 + 4 = 64
b^2 = 60
x^2/64 + y^2/60 = 1
