How To: Solve rational inequalities

In this video, we learn how to solve rational inequalities. First, you will take the problem (x-1 over x+2 is greater than 0). The first method to solve this is to think you have any number divided by another number is greater than 0. Remember the properties to solving problems. Know that both A and B have to be greater than 0 since it's a positive divided by a positive. Or, you can have a negative divided by a negative which will make a positive. The first solution is (x-1 greater than 0 and X+2 is greater than 0). The other option is if both of them were less than 0. Once you understand the properties of these equations, you can more easily solve them and do this process for all problems!
