In this tutorial the instructor talks about various strategies for solving equations and inequalities involving absolute value. To do this the first step is to isolate an absolute value. An absolute value is exactly equal to a number. If that number is less than zero then ther ...more

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 problem ...more
