Binomial theorem class 11 formula
WebAs a result, we can write (a+b) 5 = a 5 + 5a 4 b + 10a 3 b 2 + 10a 2 b 3 + 5ab 4 + b 5. The binomial expansion is made up of several terms, including: General Term is given by T r+1 = n C r a n – rbr. Middle Term. The total number of terms in an expansion of (a+b) n is n+1. The sum of the powers of a and b equals n.
