Introduction to Binomial Theorem

We have learnt how to find the squares and cubes of binomials like  a+b , a-b ,.etc.

We have to expand  (a+b)^n , where  n is a integer or rational number. This difficulty was overcome by a theorem known as Binomial Theorem.

History:

Binomial expansion for the case n=2 was used by Greek Mathematician Euclid around 300 B.C. During that period the Hindu Mathematicians also knew about the co-efficient of binomial expansion.

Sir Isaac Newton generalized the binomial theorem for negative integral and fractional indices in 1665.
