foci x^2-9y^2=9

foci

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

(10, 0), (- 10, 0)

Solution steps

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

Calculate Hyperbola properties

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

Right-left Hyperbola with

(h, k) = (0, 0), a = 3, b = 1

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

Compute

c :

c = 3^{2} + 1^{2} : 10

(0 + 10, 0), (0 - 10, 0)

Refine

(10, 0), (- 10, 0)

\frac{( x - 3 ) ^{2}}{16} - \frac{( y + 4 ) ^{2}}{1} = 1

x^{2} - 4 y^{2} = 16

\frac{( x - 5 ) ^{2}}{12} - \frac{( y + 6 ) ^{2}}{17} = 1

x^{2} - \frac{y ^{2}}{4} = 1

\frac{y ^{2}}{49} - \frac{x ^{2}}{16} = 1
