x^2+2x+y^2-18y=-57

Lösung

x^{2} + 2 x + y^{2} - 18 y = - 57

Lösung

(a, b) = (- 1, 9), r = 5

Schritte zur Lösung

x^{2} + 2 x + y^{2} - 18 y = - 57

Rewrite

x^{2} + 2 x + y^{2} - 18 y = - 57

in the form of the standard circle equation

(x - (- 1))^{2} + (y - 9)^{2} = 5^{2}

Therefore the circle properties are:

(a, b) = (- 1, 9), r = 5

(x+4)^2+(y+3)^2=9

(x + 4)^{2} + (y + 3)^{2} = 9

(x-1)^2+(y-2)^2=123.21

(x - 1)^{2} + (y - 2)^{2} = 123.21

x^2+y^2-25x-25y+100=0

x^{2} + y^{2} - 25 x - 25 y + 100 = 0

x^2+y^2-5x=12-6y

x^{2} + y^{2} - 5 x = 12 - 6 y

x^2+y^2+8x-8y-18=0

x^{2} + y^{2} + 8 x - 8 y - 18 = 0
