Box Method for Polynomial Multiplication

The video tutorial covers the multiplication of binomials using the box method. It begins with an introduction to the concept and explains how to organize the multiplication process. The teacher provides a step-by-step example of multiplying x+2 by x+2, demonstrating the use of the box method. The tutorial then extends the method to cubic polynomials, showing how to handle more complex problems. Finally, the video concludes by finalizing the polynomial, identifying its degree and terms, and ensuring students understand the process.
