The video tutorial explains synthetic division, a method for dividing polynomials by binomials of the form X - K. It covers the necessary conditions for using synthetic division, such as the divisor being a linear binomial. The tutorial highlights common mistakes, like misidentifying the value of K, and explains how to handle missing terms in polynomials by using placeholders. The process involves listing coefficients, using the opposite of K, and performing a series of multiplications and additions to find new coefficients. The video promises further examples in other videos.
