In the expansion of (x-(a/x))^5 *(x+(a/x))^5,where a is a non-zero constant,the
coefficient of the term in x^(-2) is ‘–9’ times the coefficient in x^2 .Find the value of
the constant a.

在x-(a/x))^5 *(x+(a/x))^5 的展开式中
再问: 后面还有呢……
再答: 在x-(a/x))^5 *(x+(a/x))^5 的展开式中,在这个式子中a是一个非零常数,x^(-2)项的系数是x^2项系数的-9倍。计算常数a的值。(我刚开始没看到后边的,我以为只是要翻译前面的呢!希望我的翻译能使你满意!)
