The formula I used for expansion in this problem could also be called the binomial theorem for any index or power, it works for all values of n, although the condition for convergence is strictly |x|<=1 (for ascending powers) & that's why we're able to eliminate higher powers of x.

I don't think the expansion is correct cause a half multiplied 3 times
