$$
f(0) = 2f(0)
$$
so $f(0) = 0$.
Next, differentiate the original equation with respect to $y$ alone:
$$
f'(x + y) = f'(y) + e^{x+y} + (x+y)e^{x+y} - e^y - ye^y + 2x.
$$
Put $y = 0$:
$$
f'(x) = f'(0) + e^x + xe^x - 1 + 2x = e^x + xe^x + 2x
$$
Therefore
$$
f(x) = \int\_0^x \left(e^z + ze^z + 2z\right)... | Rewrite the equation as
$f(x+y)-f(x)-f(y)=e^{x+y}(x+y)-xe^x-ye^y-2xy$
then simply note that
$f(x)=x e^x-x^2$
