Students will learn how to use polynomial long division to prove the sum of cubes and difference of cubes formulas (video). They'll also see a visual proof of each formula. Here's a visual proof for the sum, and here's one for the difference. Before attempting this section, students should know the volume formula for rectangular prisms. Students should also know how to perform polynomial long division.
