Homework Help: Algebra II Please check-

Please help-What is the equation of the ellipse with foci (0,6), (0,-6) and co-vertices (2,0),(-2,0)

Please explain the steps because I have 5 to do for homework-Thank you-I'm really stuck on this
I thought the answer would be x^2/4 + y^2/40 = 1 but that can't be because the choices are:
x^2/1 + y^2/40 = 1 or x^2/1 + y^2/36
I'm really confused

I forgot to put that I think b= 2
c=6, so therefore
a^2-2^2 = 6^2
so a= 40, that' how I got to my equation
