Operations with Rational Expressions Worksheets

Simplify rational expressions, solve rational equations and retain excluded domain values.

Before you begin

Factor polynomials, use exponent laws and solve equations with domain restrictions.

Worked example

Add 4/(x − 4) + 6/(x − 4). State the restriction.

  1. The denominators match, so add the numerators.
  2. The original denominator cannot be zero.

Answer: 10/(x − 4); x ≠ 4

Check your result using the method in the example before moving to the next question.
