You have .

First, note that .

In order to solve for , you need to consider two cases, since multiplying or dividing by a negative number reverses the inequality sign...

Case 1: .

Then

.

So in this case, you are told and . Since there are not any values of that satisfy both conditions, there are not any solutions in this case.

Case 2: .

.

So in this case, the conditions are and .

Therefore, the solution in this case is .

So the solution of your inequality is . - Mar 20th 2011, 07:53 PMpickslides
