I am trying to figure out how to write the domain in interval notation i reduced the denominator to (x-4)^2 but am stuck now any help would be great Thanks

What you have said is not entirely correct, you can reduce the denominator to thus For which value is the fraction not defined? i.e when is the denominator zero? Can you make a conclusion now?
I believe the denominator is = to zero when x = to -4 or 4 so in interval notation I got (infinity,-4) U (4, inifinity)

correction ... only x = -4 is not in the domain.
The domain is all real number excluding -4

Thank You to both of you I have been stuck on this for over a day now
