foci

(- 3, 3 + 23), (- 3, 3 - 23)

Solution steps

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

Calculate ellipse properties

16 x^{2} + 4 y^{2} + 96 x - 24 y + 116 = 0 :

Ellipse with center

(h, k) = (- 3, 3), b = 4, a = 2

(- 3, 3 + c), (- 3, 3 - c)

Compute

c :

c = 4^{2} - 2^{2} : 23

(- 3, 3 + 23), (- 3, 3 - 23)
