Your next 3 lines have nothing to do with the first equation, furthermore
they don't even make sense.
Is there a question ?
What is this " (x " ??
Please help to check if my answer below is correct.
1. x2+y2+4x-5=0
x2-4x=(x-2)2=4
y2+5=(y+3)2=9

x^2+y^2+4x-5=0
x^2+4x + y^2 = 5
x^2+4x+4 + y^2 = 9
(x+2)^2 + y^2 = 9
x^2+4x + y^2 = 5
x^2+4x+4 + y^2 = 9
(x+2)^2 + y^2 = 9
