(x^2+4x+4)+(y^2-8y+16)=-9+4+16

Lösung

(x^{2} + 4 x + 4) + (y^{2} - 8 y + 16) = - 9 + 4 + 16

Lösung

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

Schritte zur Lösung

x^{2} + 4 x + 4 + (y^{2} - 8 y + 16) = - 9 + 4 + 16

Rewrite

x^{2} + 4 x + 4 + (y^{2} - 8 y + 16) = - 9 + 4 + 16

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
