The video tutorial explains how to add polynomials by combining like terms. It begins with an introduction to polynomial terms and the concept of like terms, which are terms with the same variable factors. The instructor demonstrates how to combine these terms using a step-by-step example, emphasizing the importance of adding coefficients of like terms. The tutorial concludes with a final calculation and a summary of the process, ensuring that viewers understand how to simplify polynomial expressions by combining like terms.
