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

Lösung

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

Lösung

(a, b) = (- 2, 0), r = 2

Schritte zur Lösung

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

Rewrite

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

in the form of the standard circle equation

(x - (- 2))^{2} + (y - 0)^{2} = 2^{2}

Therefore the circle properties are:

(a, b) = (- 2, 0), r = 2

x^2+y^2+6x-10y+18=0

x^{2} + y^{2} + 6 x - 10 y + 18 = 0

4 - x^{2} - y^{2} > 0

x^2+y^2-10x+9y+1=0

x^{2} + y^{2} - 10 x + 9 y + 1 = 0

16 - x^{2} - y^{2} \geq 0

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