The "domain" is all allowable x-values, and relates tofunctions, not inequalities. Were you maybe actually supposed to find the solution intervals for therational inequality...?

Until you show your work, I'm afraid there is no way to answer this question. Sorry!

You have three different factors, one of which occurs twice. Find the zeroes of each factor. These zeroes will divide the number line into intervals.

Check the sign of the rational expression on each interval (by picking a random x-value within the interval and plugging it into the expression). The solution intervals will be those for which you got a negative value.
