Understanding Squaring Binomials

The video tutorial explains how to square a binomial, a type of polynomial with two terms. It begins by addressing common mistakes, such as incorrectly squaring each term separately. The correct method involves multiplying the binomial by itself and using the distribution method to expand it. The tutorial then demonstrates how to combine like terms to simplify the resulting polynomial. The video concludes with a summary of the process and emphasizes the importance of understanding each step.

What is a binomial?
