9x^2+16y^2+18x-135=0

Lösung

9 x^{2} + 16 y^{2} + 18 x - 135 = 0

Lösung

(h, k) = (- 1, 0), a = 4, b = 3

Schritte zur Lösung

9 x^{2} + 16 y^{2} + 18 x - 135 = 0

Rewrite

9 x^{2} + 16 y^{2} + 18 x - 135 = 0

in the form of the standard ellipse equation

\frac{( x - ( - 1 ) ) ^{2}}{4 ^{2}} + \frac{( y - 0 ) ^{2}}{3 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (- 1, 0), a = 4, b = 3

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (- 1, 0), a = 4, b = 3

3X^2+4Y^2+12X-8Y+9=0

3 X^{2} + 4 Y^{2} + 12 X - 8 Y + 9 = 0

((x+2)^2)/4+((y-3)^2)/(16)=1

\frac{( x + 2 ) ^{2}}{4} + \frac{( y - 3 ) ^{2}}{16} = 1

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