9x^2+4y^2+18x-8y-131=0

Lösung

9 x^{2} + 4 y^{2} + 18 x - 8 y - 131 = 0

Lösung

(h, k) = (- 1, 1), a = 4, b = 6

Schritte zur Lösung

9 x^{2} + 4 y^{2} + 18 x - 8 y - 131 = 0

Rewrite

9 x^{2} + 4 y^{2} + 18 x - 8 y - 131 = 0

in the form of the standard ellipse equation

\frac{( x - ( - 1 ) ) ^{2}}{4 ^{2}} + \frac{( y - 1 ) ^{2}}{6 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (- 1, 1), a = 4, b = 6

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (- 1, 1), b = 6, a = 4
