center 2x^2+3y^2-4x+6y-1=0

Lösung

center

2 x^{2} + 3 y^{2} - 4 x + 6 y - 1 = 0

(1, - 1)

Schritte zur Lösung

2 x^{2} + 3 y^{2} - 4 x + 6 y - 1 = 0

Rewrite

2 x^{2} + 3 y^{2} - 4 x + 6 y - 1 = 0

in the form of the standard ellipse equation

\frac{( x - 1 ) ^{2}}{( 3 ) ^{2}} + \frac{( y - ( - 1 ) ) ^{2}}{( 2 ) ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (1, - 1), a = 3, b = 2

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (1, - 1), a = 3, b = 2

And the center is:
