foki-9x^2+y^2+6y-27=0

Lösung

foki

- 9 x^{2} + y^{2} + 6 y - 27 = 0

(0, - 3 + 210), (0, - 3 - 210)

Schritte zur Lösung

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

Calculate Hyperbola properties

- 9 x^{2} + y^{2} + 6 y - 27 = 0 :

Up-down Hyperbola with

(h, k) = (0, - 3), a = 6, b = 2

(0, - 3 + c), (0, - 3 - c)

Compute

c :

c = 6^{2} + 2^{2} : 210

(0, - 3 + 210), (0, - 3 - 210)
