Mathematics I (Math 1132)

Sum or Difference of Cubes

Generally, the higher the degree of a polynomial, the harder it becomes to factor. The highest degree you’re expected to factor in this course are cubic equation (those raised to the power of three). Specifically, we’ll look at examples similar in structure to quadratics that are a difference of square, called a difference or sum of cubes. Their general format is displayed below:

Sum of cubes:   

a3+b3=a+ba2ab+b2

Difference of cubes: 

a3b3=aba2+ab+b2

The video below will outline how these expressions are factored:
