### proper weak form

This is a general question about FEM. Suppose I have a PDE of the from:
$\nabla^2u+\left(a\cdot\nabla\right)u=0$2u+(a·)u=0
Should the $\left(a\cdot\nabla\right)u$(a·)u  term be integrated by parts to obtain the weak form?
It would be great if someone could point me to a reference.
Thank you,
Marcin
