H3: What are Rational Expressions?

  • Educators and instructors teaching algebra and other mathematical concepts
  • For example, let's consider the rational expression: (2x^2 + 5x + 3) / (x + 3). To simplify this expression, we need to factor both the numerator and the denominator: (2x^2 + 5x + 3) = (x + 3)(2x + 1) and (x + 3) = (x + 3). Then, we can cancel out the common factor (x + 3) to get the simplified expression: (2x + 1).

    Yes, you can simplify rational expressions with variables. However, you need to follow the same rules as simplifying rational expressions with numbers.
