Your equation represents a circle
You ask to check your answer, but you don't even say what the question is.
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 " ??

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
