## Kerala Plus One Maths Notes Chapter 8 Binomial Theorem

- The coefficients of the expansions are arranged in an array. This array is called Pascal’s triangle.
- The expansion of a binomial for any positive integral n is given by Binomial Theorem.

- The coefficients of
^{n}C_{r}occuring in the binomial theorem are known as binomial coefficients. - There are (n + 1) terms in the expansion of (a + b)
^{n } - The sum of the indices of ‘a’ and ‘b’ is ‘n’ in every term of the expansion.
- (r + 1)
^{th}term is called the general term of the expansion (a+b)^{n}is denoted T_{r+1}T_{r+1 }= n C_{r }a^{n-1}b^{r } - In the expansion (a + b)
^{n } - If n is even, then the middle term is the

terms - If n is odd, then the middle terms are
