foci 9x^2-y^2=36

foci

(210, 0), (- 210, 0)

Solution steps

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

Calculate Hyperbola properties

9 x^{2} - y^{2} = 36 :

Right-left Hyperbola with

(h, k) = (0, 0), a = 2, b = 6

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

Compute

c :

c = 2^{2} + 6^{2} : 210

(0 + 210, 0), (0 - 210, 0)

Refine

(210, 0), (- 210, 0)
