Problem

Find all solutions of the inequality Express your answer in interval notation, simplifying all fractions in your answer.
Solution
We can make our work easier by rewriting all fractions in the inequality so that they have a common denominator of : Then we subtract from both sides: The expression on the left side is the positive difference between and . So, the inequality says that is strictly between and . Simplifying these expressions and writing our answer in interval notation, we have .
Final answer
\left(\frac{1}{8},\frac{1}{3}\right)
