# Binomial Expansions Question watch

1. Hey everyone, I'm stuck on this binomial questions and was wondering if anyone could help.
a) The first four terms of the binomial expansion of (1+x/4)^8 in ascending powers of x are 1 + ax + bx^2 + cx^3 . Find the values of the constants a, b and c.
b) Hence find the coefficient of x in the expansion of (1+4/x)^2 (1+x/4)^8.

I've done question a but do not know how to proceed with b. Any help would be much appreciated.
