# Chapter 6 - Section 6.6 - Solving Quadratic Equations by Factoring - Exercise Set: 71

$\frac{17}{60}$

#### Work Step by Step

Step 1: $\frac{7}{10}-\frac{5}{12}$ Step 2: A common multiple of 10 and 12 is 120. Step 3: Therefore, $\frac{7}{10}-\frac{5}{12}=\frac{12(7)-5(10)}{120}=\frac{84-50}{120}=\frac{34}{120}=\frac{17}{60}$
