Write down the first three terms, in ascending powers of xxx, of the binomial expansion of (1+px)12(1 + px)^{12}(1+px)12, where p p\,p is a non-zero constant.
Given that, in the expansion of (1+px)12(1 + px)^{12}(1+px)12, the coefficient of x x\,x is (−q)(-q)(−q) and the coefficient of x2 x^2\,x2 is 11q11q11q, find the value of p p\,p and the value of qqq.
