Hi

Ellipse:

4x^2 + 8y^2 = 32 



 Standard Form of an Equation of an Ellipse is where Pt(h,k) is the center

 and a and b  are the respective vertices.. Distances from center.

Center is (0,0)

Vertices:  (sqrt(8),0) and (-sqrt(8),0)  AND (0,2) and (0-2)

foci: (2,0) and (-2,0)    c = 

length of major axis is : 2sqrt(8)

length of minor axis is : 2*2 = 4
