x^2+4x+y^2-6y=-4 (x^2+4x)+(y^2-6y)=-4 (4/2)^2=4 (6/2)^2=9 (x^2+4x+4)+(y^2-6y+9)=-4+(4+9) (x^2+4x+4)+(y^2-6y+9)=9 (x+2)^2+(y-3)^2=3^2 center=(-2.3) Radius=3

(x^2+4x)+(y^2-6y)=-4
(4/2)^2=4
(6/2)^2=9
(x^2+4x+4)+(y^2-6y+9)=-4+(4+9)
(x^2+4x+4)+(y^2-6y+9)=9
(x+2)^2+(y-3)^2=3^2
center=(-2.3) Radius=3
@katrin369 You sure it's not 6..?
Yes I'm sure.
@honda put in 3 but if it's wrong try 6
