Adding and Subtracting Rational Expressions

The video tutorial covers the process of dividing polynomials using long division. It begins with a review of long division with basic numbers, then transitions to polynomial long division. The tutorial provides step-by-step examples, including handling missing powers and dealing with remainders. The instructor emphasizes the importance of placeholders for missing terms to avoid errors.
