Adding and Subtracting Rational Expressions with Polynomials - Lecture and Problem Set

Master the concepts of adding and subtracting rational expressions in this comprehensive mathematics lecture and problem-solving session. Learn the essential technique of finding least common denominators (LCD) through polynomial factoring, and understand how to multiply missing quantities across numerators and denominators. Practice working with complex fractions by applying common denominators within separate numerator and denominator components before converting to division problems. Explore graphing techniques, including the transformation from y = (ax + b)/(cx + d) form to y = a/(x - h) + k form using inspection methods. Work through 58 diverse problems, including word problems, that reinforce concepts from previous lessons on rational functions and expressions. Access downloadable textbook materials and follow along with clearly marked timestamps for each problem set, making it easy to review specific concepts or work through the entire nearly 3-hour mathematical exploration at your own pace.
