foci 11x^2-7y^2=77

foci

11 x^{2} - 7 y^{2} = 77

(32, 0), (- 32, 0)

Solution steps

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

Calculate Hyperbola properties

11 x^{2} - 7 y^{2} = 77 :

Right-left Hyperbola with

(h, k) = (0, 0), a = 7, b = 11

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

Compute

c :

c = 7^{2} + 11^{2} : 32

(0 + 32, 0), (0 - 32, 0)

Refine

(32, 0), (- 32, 0)

9 x^{2} - 4 y^{2} = 144

\frac{( x - 5 ) ^{2}}{16} - \frac{( y - 4 ) ^{2}}{64} = 1

8 x^{2} - 2 y^{2} = 16

4 x^{2} - 12 y^{2} - 16 x - 72 y - 44 = 0

- 25 x^{2} + 36 y^{2} = 900
