Integration By Parts (exponent included)

∫ 4xye-(x² + y²)  dy   with the -(x² + y²) being the power of the exponent.

can someone help me how to solve this? integration by parts is needed to solve this :- ∫udv/dx + ∫vdu/dx = uv

and the answer to that is

Note that you are integrating with respect to y only, so treat the x as a constant.
