Understanding Polynomials and Binomials

The video tutorial, hosted by Sean E, introduces the concept of binomials, explaining that a binomial is a polynomial with exactly two terms. The video details what constitutes a term, including numerals, variables, and their combinations. Examples are provided to illustrate how to identify binomials, such as '3x + 4' and 'x + 5'. The tutorial also explains that multiplying binomials can result in polynomials with more than two terms, thus not qualifying as binomials. The video concludes with a call to action for viewers to engage and subscribe.
