x^2+y^2+2x-8y+12=0

Lösung

x^{2} + y^{2} + 2 x - 8 y + 12 = 0

Lösung

(a, b) = (- 1, 4), r = 5

Schritte zur Lösung

x^{2} + y^{2} + 2 x - 8 y + 12 = 0

Rewrite

x^{2} + y^{2} + 2 x - 8 y + 12 = 0

in the form of the standard circle equation

(x - (- 1))^{2} + (y - 4)^{2} = (5)^{2}

Therefore the circle properties are:

(a, b) = (- 1, 4), r = 5
