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

foci

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

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

Solution steps

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

Calculate Hyperbola properties

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

Right-left Hyperbola with

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

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

Compute

c :

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

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

Refine

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

\frac{( y - \frac{9}{2} ) ^{2}}{49} - \frac{( x - \frac{7}{2} ) ^{2}}{49} = 1

9 x^{2} - 4 y^{2} + 18 x - 27 = 0

\frac{x ^{2}}{8} - \frac{y ^{2}}{8} = 1

\frac{y ^{2}}{64} - \frac{x ^{2}}{49} = 1

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