2+((x^2)/(1-x))
$$2+\frac{x^2}{1-x}$$
To work out the domain, the idea is to work out what x can be.
It is usually easier to work out what x can't be though.
So with this one.
you cannot divide by zero so
$$\\1-x\ne 0\rightarrow\;\;x\ne 1$$
Domain: All Real x where x is not equal to 1
or
Domain: All Real x except x=1
I think x can be anything else, I will double check by graphing it.

Yes that is fine :)
