Parenthesis again.
[rant]
$\displaystyle \int 8x + 5 sin(x)~dx$ is not a valid expression. $\displaystyle \int (8x + 5 sin(x))~dx$ is!!!!

Thank you for your time.

Great example, thanks! However:
[Gotcha_mode=ON]
"Parenthesis" is singular, as in one mark "(" or ")." "Parentheses" is plural. Typically math expressions use parentheses in pairs, though a bracket and a single parenthesis may be used to denote a half-closed interval as in [3,8).
