You can put this solution on YOUR website! x can be any number but it cannot be 0 or -5. Why those two restrictions? Because if x = 0, then you have a division by zero error. Same reason for x = -5.
So the domain in interval notation is: \cup(-5,0)\cup(0,\infty))

***
Denominators ≠ 0
set denominators=0 and solve for x
x≠0
x+5=0
x≠-5
domain:(-∞,-5) U (-5,0) U (0,∞)

Domain::
x cannot be 0 ; x cannot be -5
----
Ans:: (-oo,-5)U(-5,0)U(0,+oo)
