BINOMIAL THEOREM FOR POSITIVE INTEGRAL INDEX
If x and a are real, then “n ϵ N i.e (x + a)n = nC₀xn + nC₁.xn-¹a+nC₂xm-².a²+ … +nCrxn-r.ar + … + nCn.x⁰an(x + a)n =. 1. General term for (1 + x)nis Tr + 1= nCr.xr 2. In the binomial expansion of (x + a)n, rthterm from end is (n – r + 2)th term from beginning Read more about BINOMIAL THEOREM FOR POSITIVE INTEGRAL INDEX[…]
