x^2+y^2+2x+2y-4=0

Lösung

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

Lösung

(a, b) = (- 1, - 1), r = 6

Schritte zur Lösung

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

Rewrite

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

in the form of the standard circle equation

(x - (- 1))^{2} + (y - (- 1))^{2} = (6)^{2}

Therefore the circle properties are:

(a, b) = (- 1, - 1), r = 6

36x^2-36+36y^2+72y=279

36 x^{2} - 36 + 36 y^{2} + 72 y = 279

x^2+y^2-2x-6y-3=0

x^{2} + y^{2} - 2 x - 6 y - 3 = 0

25 = x^{2} + y^{2}

(x-8)^2+(y-5)^2= 16/9

(x - 8)^{2} + (y - 5)^{2} = \frac{16}{9}

(x - 1)^{2} + y^{2} = 16
