The inequality is in standard form already (i.e., one side of the inequality is equal to zero).
The critical numbers are:
-2/3, 7/2, and 5.
(, -2/3): . (Choose test number x = -1.)
( -2/3, 7/2): . (Choose test number x = 0).
(7/2, 5): . (Choose test number x = 4.)

(5, ): . (Choose test number x = 6.)
The critical numbers -2/3 and 5 also satisfy the inequality, but not 7/2. Hence the solution set is the union
(, 7/2) U [5, ).
