If `n` is an even positive integer, then find the value of `x` if the greatest term in the expansion of `(1+x) ^n` may have the greatest coefficient also.

If n is an even positive integer greater than 1 and x gt0 , then the condition that the greatest term in the expansion of (1+x)^(n) may have the greatest coefficient also is
