    How do I handle rational expressions with different variables?

  • Misconception 1: Rational expressions can only be added and subtracted if they have the same denominator.
  • Misconception 2: Simplifying rational expressions always results in a simpler expression.

    • When working with rational expressions that have different variables, you need to use the least common multiple (LCM) of the denominators to find a common denominator. Then, combine the numerators and simplify the expression.

    To simplify complex rational expressions, start by factoring the numerator and denominator. Then, cancel out any common factors and simplify the remaining expression.

      Adding and subtracting rational expressions involves combining or simplifying expressions with different denominators. The key is to find a common denominator and then combine the numerators. For example, consider the expression: (2x + 3) / (x + 1) + (x - 2) / (x + 1). To add these expressions, we first need to find a common denominator, which is (x + 1). Then, we can combine the numerators: (2x + 3) + (x - 2) = 3x + 1. Therefore, the simplified expression is (3x + 1) / (x + 1).

      When adding rational expressions, you are combining them, whereas subtracting rational expressions involves finding the difference between them. To subtract rational expressions, you need to find a common denominator and then subtract the numerators.
