In this lesson, the instructor provides more examples of dividing polynomials using long division. Instead of estimating, the instructor shows how to multiply the first term outside to get the first term inside. The instructor explains how to subtract while doing the division, and reminds the viewer to always stay in descending order. The instructor provides step-by-step instructions on how to write the answer in the correct form and even shows how to check the answer to make sure it is correct.
This is Part 4 of Dividing Polynomials using long division, which shows more examples, and shows the subtraction part a little differently than shown in Part 2.
