Here you will learn formula to find middle term in binomial expansion with examples. Let’s begin – Middle Term in Binomial Expansion Since the binomial expansion of \((x + a)^n\) contains (n + 1) terms. Therefore, (1) If n is even, then \({n\over 2} + 1\) th term is the middle term. (2) If n …
Here you will learn formula for binomial theorem of class 11 with examples. Let’s begin – Formula for Binomial Theorem If x and a are real numbers, then for all n \(\in\) N. \((x + a)^n\) = \(^{n}C_0 x^n a^0\) + \(^{n}C_1 x^{n – 1} a^1\) + …………… + \(^{n}C_r x^{n – r} a^r\) + …………… …
Here you will learn formula to find the general term in binomial expansion with examples. Let’s begin – General Term in Binomial Expansion We have, \((x + a)^n\) = \(^{n}C_0 x^n a^0\) + \(^{n}C_1 x^{n – 1} a^1\) + …………… + \(^{n}C_r x^{n – r} a^r\) + …………… + \(^{n}C_n x^0 a^n\) We find that …
