x^2+4y^2+8x+8y-16=0

Lösung

x^{2} + 4 y^{2} + 8 x + 8 y - 16 = 0

Lösung

(h, k) = (- 4, - 1), a = 6, b = 3

Schritte zur Lösung

x^{2} + 4 y^{2} + 8 x + 8 y - 16 = 0

Rewrite

x^{2} + 4 y^{2} + 8 x + 8 y - 16 = 0

in the form of the standard ellipse equation

\frac{( x - ( - 4 ) ) ^{2}}{6 ^{2}} + \frac{( y - ( - 1 ) ) ^{2}}{3 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (- 4, - 1), a = 6, b = 3

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (- 4, - 1), a = 6, b = 3
