Answer:
Answer:
b_{0}=b_{n}b

,
b_{1}=b_{n-1}b

n−1
b_{2}=b_{n-2}b

=b
n−2
and so on.
Step-by-step explanation:
Let us assume that the n degree function be q(z)=(1+z)^{n}q(z)=(1+z)
n
.
Now this function can be expanded using binomial theorem as
(1+z)^{n}=b_{0}+b_{1}z+b_{2}z^{2}+b_{3}z^{3}+.........+b_{n-1}z^{n-1}+b_{n}z^{n}(1+z)
n
=b

Where, b_{0}, b_{1}, b_{2},b

,b
n
are the coefficients of 1st, 2nd, 3rd,....... upto (n+1)th terms of the expansion.
The conditions for equation (1) to be valid only if n is a positive integer.
And the conditions on the coefficients are that,
b_{0}=b_{n}b
0
=b
n
,
b_{1}=b_{n-1}b

=b
n−1
b_{2}=b_{n-2}b

=b
n−2
and so on.
