Binomial theorem

Binomial Theorem:

According to Binomial theorem, it is possible to expand any power of x + y into a sum of the for

where indicates the corresponding binomial coefficient.By using the summation notation ,the above formula can be written as

A variant of the binomial formula is obtained by substituting  1 for x and x for y, so that it involves only a single variable. In this form, the formula reads
