We have learnt how to find the squares and cubes of binomials like ,.etc.
We have to expand , where is a integer or rational number. This difficulty was overcome by a theorem known as Binomial Theorem.
Binomial expansion for the case 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.
