9x^2+25y^2+90x=0

Lösung

9 x^{2} + 25 y^{2} + 90 x = 0

Lösung

(h, k) = (- 5, 0), a = 5, b = 3

Schritte zur Lösung

9 x^{2} + 25 y^{2} + 90 x = 0

Rewrite

9 x^{2} + 25 y^{2} + 90 x = 0

in the form of the standard ellipse equation

\frac{( x - ( - 5 ) ) ^{2}}{5 ^{2}} + \frac{( y - 0 ) ^{2}}{3 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (- 5, 0), a = 5, b = 3

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (- 5, 0), a = 5, b = 3
