-4x^2-y^2+8x-4y+8=0

Lösung

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

Lösung

(h, k) = (1, - 2), a = 2, b = 4

Schritte zur Lösung

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

Rewrite

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

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

(h, k) = (1, - 2), a = 2, b = 4

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (1, - 2), b = 4, a = 2
