Learn how to add two different polynomials by adding like terms

The video tutorial covers the process of subtracting polynomials, emphasizing the importance of aligning terms vertically for easier computation. It begins with a review of basic addition concepts, using vertical alignment as a method to simplify the process. The tutorial then explains how to align polynomials vertically, ensuring like terms are in descending order. It introduces the use of placeholders for missing terms to maintain alignment. Finally, the tutorial demonstrates the complete addition of polynomials, highlighting the importance of writing the result in descending order.
