foci ((x-12)^2)/(289)+((y-3)^2)/(64)=1

foci

(27, 3), (- 3, 3)

Solution steps

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

Calculate ellipse properties

\frac{( x - 12 ) ^{2}}{289} + \frac{( y - 3 ) ^{2}}{64} = 1 :

Ellipse with center

(h, k) = (12, 3), a = 17, b = 8

(12 + c, 3), (12 - c, 3)

Compute

c :

c = 1 7^{2} - 8^{2} : 15

(12 + 15, 3), (12 - 15, 3)

Refine

(27, 3), (- 3, 3)
