Not important unless you need x to be a certain value. Only two meaningful options for placing parentheses, at best.

28-%283x%5E3%2B4%29=79 will make x+=+root%283%2C%28-55%2F3%29%29 .

%2828-3x%5E3%29%2B4=28-3x%5E3%2B4=79 will make x+=+root%283%2C%28-47%2F3%29%29.

Nothing more. Only one option has any effect on meaning of the expression.
