This instructor in this video, Sal Khan, discusses adding and subtracting polynomials. In an easy, conversational tone, the instructor explains processes clearly. (15:59)
Mr. Khan uses the Paint Program (with different colors) to illustrate his p...oints. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education. The student or educator may want to open the video to 'full screen' as the instructor is using a black background and the writing is small.[more]

This lesson is part of a series: Beginner Algebra
In this lesson, we learn how to add and subtract polynomials. A very important tip to keep in mind is to simplify the polynomial by combining like terms (terms with the same variable raised to the s...ame power). When adding or subtracting strings of polynomials, you are simply combining the individual factors. Remember when subtracting that you need to distribute the subtraction sign to every factor within the parentheses.
Taught by Professor Edward Burger, this lesson was selected from a broader, comprehensive course, Beginning Algebra.[more]

In this video, the instructor defines polynomials, then gives some examples of how to add and subtract polynomials. He works through the steps of example problems to explain how to work add and subject polynomials. His explanations are clear and th...orough and it would be easy to follow along as he explains.[more]

This five minute video uses a narrator and an enlarged white paper to show these operations. It moves rapidly and so the video may have to be stopped to review each step.
