Question
can you pls tell the formulas in binomial theorem
Answers
Reiny
if you mean the binomial expansion...
(a+b)^n
= a^n + C(n,1)a^(n-1) b + C(n,2) a^(n-2) b^2 +... C(n, n-1) a^1 b^(n-1) + b^n
or , for a general value of n
= a^ + n a^(n-1) b + n(n-1)/2! a^(n-2)b^2 + n(n-1)(n-2)/3! a^(n-3) b^3 + ....
(a+b)^n

= a^ + n a^(n-1) b + n(n-1)/2! a^(n-2)b^2 + n(n-1)(n-2)/3! a^(n-3) b^3 + ....
