foci (x^2)/4+(y^2)/(20)=1

foci

(0, 4), (0, - 4)

Solution steps

(h, k + c), (h, k - c)

Calculate ellipse properties

\frac{x ^{2}}{4} + \frac{y ^{2}}{20} = 1 :

Ellipse with center

(h, k) = (0, 0), b = 25, a = 2

(0, 0 + c), (0, 0 - c)

Compute

c :

c = (25)^{2} - 2^{2} : 4

(0, 0 + 4), (0, 0 - 4)

Refine

(0, 4), (0, - 4)
