The Meaning of a Binomial

If an algebraic expression contains two terms added or subtracted to each other, it is called a binomial. We will discuss binomials more extensively in chapter 11. For now, we focus only on the definition. Thus, by definition, a binomial is an algebraic expression of the sum or the difference of two terms.

In symbols, a binomial is written as a + b, where a and b may represent a single number, a single variable, a product of numbers and variables where the latter can be raised in a certain power, etc.

For example, in the binomial

we have

and

In this tutorial we will discover eight algebraic identities based on the binomial structure that are widely used in many exercises involving expressions. Let's explain them one by one.
