What is the coefficient of the last term in the binomial expansion of (x + 1)9? 0 1 9 10

The first and last terms have coefficients of 1. The coefficient of the n-th term is C(9, n-1) = 9!/((n-1)!(10-n)!) for n=1 to 10.

The appropriate choice is ...

... 1

1

Step-by-step explanation:

Given :

To Find : What is the coefficient of the last term in the binomial expansion of (x + 1)9?  

Solution :

Formula of expansion :

So , in the last term k =9

Thus the coefficient of last term is 1.

Hence option 2 is correct

answer: i guess 105 degrees?
