4x^2+9y^2-40x+54y+145=0

Lösung

4 x^{2} + 9 y^{2} - 40 x + 54 y + 145 = 0

Lösung

(h, k) = (5, - 3), a = 3, b = 2

Schritte zur Lösung

4 x^{2} + 9 y^{2} - 40 x + 54 y + 145 = 0

Rewrite

4 x^{2} + 9 y^{2} - 40 x + 54 y + 145 = 0

in the form of the standard ellipse equation

\frac{( x - 5 ) ^{2}}{3 ^{2}} + \frac{( y - ( - 3 ) ) ^{2}}{2 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (5, - 3), a = 3, b = 2

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (5, - 3), a = 3, b = 2
