Factoring - Rational Expressions

The lesson focuses on simplifying rational expressions, a crucial skill for solving algebraic problems on the GRE exam.
  • Rational expressions are ratios of two algebraic expressions that often require simplification for problem-solving.
  • Simplification involves factoring both the numerator and the denominator and then canceling out common factors.
  • In cases where direct factoring is not possible due to different variables, separating the numerator by addition or subtraction can facilitate simplification.
  • Practical examples illustrate the process of simplification, including strategies for dealing with complex expressions involving multiple variables.
  • Practice questions underscore the importance of recognizing opportunities to simplify expressions, which can significantly streamline problem-solving.
