To Find: The ninth term of the form
Answer to Problem 16WE
The required 9th term of the binomial form
Explanation of Solution
Given Information:
The eight term is
In this given case the term 8th and the term 9th have same coefficient, as there are 16 terms in the expansion of the form.
It is also to be noted that the powers of the binomial expansion also get switched symmetrically. The alternating minus sign is not at all treated as a part of the coefficient.
So, the alternating minus sign will come about because of changing power on
Hence, the 9th term of the binomial form
