foci 9x^2-4y^2=144

foci

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

(213, 0), (- 213, 0)

Solution steps

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

Calculate Hyperbola properties

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

Right-left Hyperbola with

(h, k) = (0, 0), a = 4, b = 6

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

Compute

c :

c = 4^{2} + 6^{2} : 213

(0 + 213, 0), (0 - 213, 0)

Refine

(213, 0), (- 213, 0)

\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

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