Khan Academy: "Addition and Subtraction of Polynomials"

Watch this video and take notes. In this video, you will see examples of polynomial expressions of various degrees and number of terms. Then, you will work through two examples of adding and subtracting two polynomials. You will notice that all you have to do to add or subtract polynomials horizontally is open the parentheses (in case of subtraction) and combine like terms. This video also contains an example of applications of polynomials in geometry.
