x^2+y^2-8y+4x+9=0

Lösung

x^{2} + y^{2} - 8 y + 4 x + 9 = 0

Lösung

(a, b) = (- 2, 4), r = 11

Schritte zur Lösung

x^{2} + y^{2} - 8 y + 4 x + 9 = 0

Rewrite

x^{2} + y^{2} - 8 y + 4 x + 9 = 0

in the form of the standard circle equation

(x - (- 2))^{2} + (y - 4)^{2} = (11)^{2}

Therefore the circle properties are:

(a, b) = (- 2, 4), r = 11
