Chapter 8 Bionomial Theorem
An algebraic expression containing two terms and connected by (+) & (-) operation is called binomial. When small positive powers are raised to a binomial it can be solved manually. For higher powers it becomes very difficult to solve. But the binomial theorem helps to solve expressions which have large powers. It has many applications like in permutation and combination, probability, etc. The topics which are included in this chapter - proof of binomial theorem for positive integral indices, Pascal's triangle, general and middle term in binomial expansion and its applications.
