How to simplify result from domain function
I use domain() function to find the domain of function Sqrt(x^2-9)/(x-3)

The calculator returns result [x<=-3 x>=3 and x <>3]

When simplify, it is expected to have [x<=-3 x>3], but the calculator returns result [x<=-3 x>=3]

How can we have correct simplified answer?
