foci ((x-6)^2)/(16)+((y+3)^2)/(25)=1

foci

(6, 0), (6, - 6)

Solution steps

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

Calculate ellipse properties

\frac{( x - 6 ) ^{2}}{16} + \frac{( y + 3 ) ^{2}}{25} = 1 :

Ellipse with center

(h, k) = (6, - 3), b = 5, a = 4

(6, - 3 + c), (6, - 3 - c)

Compute

c :

c = 5^{2} - 4^{2} : 3

(6, - 3 + 3), (6, - 3 - 3)

Refine

(6, 0), (6, - 6)
