Write the standard equation of the ellipse with the given characteristics
Center:(0,0)
foci: (2,0) (2,0)
vertices:(5,0) (5,0)

looks like the vertices and the foci are on the xaxis, so this is easy
a = 5, b = ? and c = 2
In this type of ellipse,
b^2 + c^2 = a^2
b^2 + 4 = 25
b^2 = 21
x^2 /25 + y^2/21 = 1
