This video tutorial covers synthetic division, a method for dividing polynomials. It begins with an introduction to the concept and its applications, followed by detailed examples of synthetic division and confirmation using long division. The video also explores evaluating functions using the remainder theorem and factoring polynomials. Advanced examples demonstrate complex polynomial division, and the quadratic formula is applied to unfactorable trinomials. The tutorial concludes with a final example and summary of key concepts.
