Revision Notes For CBSE Class 11 Maths Chapter 8 Binomial Theorem

Class 11 Maths Revision Notes Chapter 8 Binomial Theorem consists of all the important theories and explanations related to this chapter. Students will be benefiting from this notes when it comes to getting some clarity with respect to this chapter. We are aware of the definition of Binomial Theorem:

  • The binomial theorem is used to expand binomial expressions (a + b) raised to any given power without direct multiplication. For example: (a + b)3 = a3 + 3 a2b + 3 ab2 + b3 Starting with the first term and progressing to the last, the exponent of a decrease by one while the exponent of b increases by one, and the sum of the exponents of a and b in each term is n. The binomial coefficients form a pattern of 1 3 3 1. The coefficients correspond with the rows of Pascal’s triangle and are determined by a formula involving factorials.

These observations form the basis of the binomial theorem in its expanded form:
