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

Lösung

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

Lösung

(a, b) = (- 4, - 2), r = 26

Schritte zur Lösung

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

Rewrite

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

in the form of the standard circle equation

(x - (- 4))^{2} + (y - (- 2))^{2} = (26)^{2}

Therefore the circle properties are:

(a, b) = (- 4, - 2), r = 26
