**Factoring - Rational Expressions**

Summary

The essence of the content revolves around simplifying rational expressions, a critical skill for tackling GMAT algebra questions.

- Rational expressions are ratios of two algebraic expressions that often require simplification for GMAT problems.
- Simplification involves factoring both the numerator and the denominator and then canceling out common factors.
- When expressions involve addition or subtraction in the numerator, they can be split into separate fractions with a common denominator for further simplification.
- Practical examples illustrate the process of simplification, including dealing with expressions that contain different variables and require strategic manipulation.
- Practice questions underscore the importance of recognizing opportunities to simplify by canceling common factors, significantly easing the solution process.
