This one has a restriction at x=9. THAT means you must cut the solution into TWO intervals. The inequality you have is undefined at x=9.

Further, the solution does not include x=-2, so you must use left parenthese of the curved type, not the square type.

Solving the inequality results in:
Inequality is UNDEFINED at:
Therefore, critical points are:
Test intervals: ; ; and
Thus, POSSIBLE test values are: ; ; and
Any test value that's included in any of the above imtervals, and which makes the inequality TRUE will be your answer(s).
