Algebra 88 - Adding and Subtracting Polynomial Functions

Adding polynomial functions produces another polynomial function. The values of this function are the sum of the values of the polynomials that were added for every possible value of the input variable(s). Fortunately, adding polynomial functions is a lot easier than adding their values at every point. In this lecture we will see how to perform polynomial addition, and see how this process can produce graphically interesting and sometimes unexpected results.
