Multiplying and Dividing Rational Expressions - Lesson 6.3

Learn to multiply and divide rational expressions in this comprehensive mathematics lecture and problem-solving session. Master essential algebraic concepts including handling fractions with variables, understanding restrictions on denominators to avoid division by zero, converting division problems to multiplication using reciprocals, and proper cancellation of common factors. Work through nearly 50 practice problems with detailed explanations, starting from basic concepts and progressing to more complex applications. Understand why multiplication and division of rational expressions are taught before addition and subtraction, and learn to identify when terms can and cannot be cancelled in algebraic fractions. Access accompanying textbook materials and follow along with timestamped sections covering each problem set for efficient learning and review.
