(4 + 5, 2), (4 - 5, 2)

Schritte zur Lösung

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

Calculate ellipse properties

4 x^{2} + 9 y^{2} - 32 x - 36 y + 64 = 0 :

Ellipse with center

(h, k) = (4, 2), a = 3, b = 2

(4 + c, 2), (4 - c, 2)

Compute

c :

c = 3^{2} - 2^{2} : 5

(4 + 5, 2), (4 - 5, 2)

f oc i 9 x^{2} - 54 x + y^{2} + 2 y + 46 = 0

f oc i \frac{x ^{2}}{8 ^{2}} + \frac{y ^{2}}{4 ^{2}} = 1

f oc i \frac{( x - 2 ) ^{2}}{9} + \frac{( y + 1 ) ^{2}}{36} = 1

f oc i \frac{( x - 6 ) ^{2}}{16} + \frac{( y + 3 ) ^{2}}{25} = 1

f oc i 9 x^{2} + 36 y^{2} = 324
