Just cross multiply and you will get a cubic equation on one side and zero on the other. Just need to be careful of the direction of the inequality sign. Next, solve for all factors of the cubic equation to give you the answer which in this case, it only has 1 linear factor (ax-b). Once you have the answer, always check back at the question since anything divided by zero will give you infinity so your value of x cannot be -2 or 1 but in this case, it would not matter since x is greater than or equal to 2.
