Start with the given function


Set the denominator equal to zero

Factor the left side (note: if you need help with factoring, check out this solver)



Now set each factor equal to zero:

or

or Now solve for x in each case


Since or make the denominator equal to zero, that means we must exclude these values from the domain.

So our domain is: x is the set of all real numbers except or


Which looks like this in interval notation:
