Find the Foci (x^2)/73-(y^2)/19=1

foci

(223, 0), (- 223, 0)

Solution steps

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

Calculate Hyperbola properties

\frac{x ^{2}}{73} - \frac{y ^{2}}{19} = 1 :

Right-left Hyperbola with

(h, k) = (0, 0), a = 73, b = 19

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

Compute

c :

c = 73^{2} + 19^{2} : 223

(0 + 223, 0), (0 - 223, 0)

Refine

(223, 0), (- 223, 0)
