# Statement of Binomial Theorem

It is possible to expand any non-negative power of is the sum of the form, i.e.,

where , and each is a positive integer known as Binomial Co-efficient.

This formula is also referred to as the Binomial Formula or Binomial Identity.

Using Summation Notation, it can be written as

Proving the above formula by Binomial Theorem.
