If a and b are real numbers and n is a positive integer, then (a + b)n =nC0 an + nC1 an – 1 b1 + nC2 an – 2 b2 + 1. The total number of terms in the binomial expansion of (a + b)n is n + 1, i.e. one more than the exponent n.

What is the formula of a B n?

If a and b are real numbers and n is a positive integer, then (a + b)n =nC0 an + nC1 an – 1 b1 + nC2 an – 2 b2 + 1. The total number of terms in the binomial expansion of (a + b)n is n + 1, i.e. one more than the exponent n.

Is binomial theorem important for JEE?

Binomial Theorem is one of the most important chapters of Algebra in the JEE syllabus.In that practice the problems which covers its properties,coefficient of a particular term,binomial coefficients,middle term,greatest binomial coefficient etc.. All the best!!

What is a B n expanded?

The Binomial Expansion The binomial expansion tells us how to write the expression (a+b)N in terms of a sum of various powers of a and b. The way to do this in principle is just to write out all the factors and expand term by term. For example. (a+b)2 = (a+b) x (a+b) = a x (a+b) + b x (a+b)
