oh yeah, it should be added, because its (x^2/a)e^ax - ((2x/a^2)e^ax - ∫ (2/a)e^ax) so its + the third term. sorry my bad, fixed it 
i always forget those little minus signs... *sigh*

#8 this is probably totally wrong but:
(x^2/a)e^ax - (2x/a^2)e^ax + (2/a^3)e^ax + C
sorry for the rubbish way of typing it... wish i knew how to put in the proper formula font :S
