foki

\frac{x ^{2}}{8} + \frac{y ^{2}}{5} = 1

(3, 0), (- 3, 0)

Schritte zur Lösung

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

Calculate ellipse properties

\frac{x ^{2}}{8} + \frac{y ^{2}}{5} = 1 :

Ellipse with center

(h, k) = (0, 0), a = 22, b = 5

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

Compute

c :

c = (22)^{2} - 5^{2} : 3

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

(3, 0), (- 3, 0)

f oc i \frac{x ^{2}}{81} + \frac{y ^{2}}{25} = 1

f oc i 81 x^{2} + 49 y^{2} = 3969

f oc i \frac{( x - 2 ) ^{2}}{2} + \frac{( y - 1 ) ^{2}}{8} = 1

f oc i \frac{( x + 2 ) ^{2}}{64} + \frac{( y - 1 ) ^{2}}{81} = 1

f oc i 9 x^{2} + 16 y^{2} + 72 x + 128 y + 256 = 0
