2x^2-4x+2y^2+18y=7

Lösung

2 x^{2} - 4 x + 2 y^{2} + 18 y = 7

Lösung

(a, b) = (1, - \frac{9}{2}), r = \frac{3 11}{2}

Schritte zur Lösung

2 x^{2} - 4 x + 2 y^{2} + 18 y = 7

Rewrite

2 x^{2} - 4 x + 2 y^{2} + 18 y = 7

in the form of the standard circle equation

(x - 1)^{2} + (y - (- \frac{9}{2}))^{2} = (\frac{3 11}{2})^{2}

Therefore the circle properties are:

(a, b) = (1, - \frac{9}{2}), r = \frac{3 11}{2}

(x-6)^2+(y-10)^2=5

(x - 6)^{2} + (y - 10)^{2} = 5

x^{2} + y^{2} - 6 y = 7

2 x^{2} - 6 x + 2 y^{2} = 0

(x^2-4x)+(y^2-6y)=23

(x^{2} - 4 x) + (y^{2} - 6 y) = 23

(x+2)^{(2)}+(y+5)^{(2)}=144

(x + 2)^{(2)} + (y + 5)^{(2)} = 144
