foci (x^2}{16}+\frac{y^2)/7 =1

foci

(3, 0), (- 3, 0)

Solution steps

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

Calculate ellipse properties

\frac{x ^{2}}{16} + \frac{y ^{2}}{7} = 1 :

Ellipse with center

(h, k) = (0, 0), a = 4, b = 7

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

Compute

c :

c = 4^{2} - 7^{2} : 3

(0 + 3, 0), (0 - 3, 0)

Refine

(3, 0), (- 3, 0)
