check your text. The ellipse
(x-h)^2/a^2 + (y-k)^2/b^2 has
center: (h,k)
semi-axes a and b
c^2 = a^2-b^2
foci are at ±c away from the center, along the major axis.
eccentricity = c/a
So, plug in your numbers. What do you get?

And what have you got so far?
BTW, the ellipse should be an equation of the type
(x+3)^2/12 + (y-2)^2/16 = 1
