Dividing two polynomials using synthetic division

This video tutorial explains how to divide polynomials using synthetic division. It begins with an introduction to the concept, emphasizing the need for a linear divisor. The tutorial then guides viewers through setting up the division process, including identifying coefficients and handling missing terms. The main section details the step-by-step execution of synthetic division, highlighting the importance of adding vertically instead of subtracting. Finally, the video covers how to interpret the results, including the quotient and remainder, and how to express the remainder over the divisor.

Explain the process of adding vertically in synthetic division.

What is the final result of the synthetic division process described?
