foci 2x^2-y^2=4

foci

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

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

Solution steps

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

Calculate Hyperbola properties

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

Right-left Hyperbola with

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

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

Compute

c :

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

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

Refine

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

9 y^{2} - 4 x^{2} - 36 y - 8 x = 4

x^{2} - 4 y^{2} = 36

\frac{x ^{2}}{36} - \frac{y ^{2}}{9} = 1

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

\frac{x ^{2}}{36} - \frac{y ^{2}}{13} = 1
