foci 7x^2-9y^2-14x+72y-200=0

foci

7 x^{2} - 9 y^{2} - 14 x + 72 y - 200 = 0

(5, 4), (- 3, 4)

Solution steps

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

Calculate Hyperbola properties

7 x^{2} - 9 y^{2} - 14 x + 72 y - 200 = 0 :

Right-left Hyperbola with

(h, k) = (1, 4), a = 3, b = 7

(1 + c, 4), (1 - c, 4)

Compute

c :

c = 3^{2} + 7^{2} : 4

(1 + 4, 4), (1 - 4, 4)

Refine

(5, 4), (- 3, 4)

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

\frac{x ^{2}}{25} - \frac{y ^{2}}{49} = 1

\frac{x ^{2}}{4} - \frac{y ^{2}}{25} = 1

\frac{y ^{2}}{1} - \frac{x ^{2}}{15} = 1

\frac{( x + 4 ) ^{2}}{4} - \frac{( y - 1 ) ^{2}}{25} = 1
