Exploring Synthetic Division in Algebra 2

The video tutorial introduces synthetic division as a faster alternative to long division for polynomials. It explains the process of synthetic division, including changing the sign of the divisor and working with coefficients. The tutorial provides step-by-step instructions and examples to illustrate the method. It also covers the remainder theorem and its application in synthetic division, emphasizing the efficiency and reduced error potential of this method.
