We will present the relations that show how the sum of two terms that are cubed can be written as a binomial multiplied by a trinomial. There is a similar expression for two cubed terms that are subtracted (the difference of two cubes) which is also introduced. These relations are very useful for simplifying expressions, solving equations, and other more advanced topics in algebra.
