1. ## integration help!

how does one integrate
∫x(x+2)e^x dx
answer ends up x^2e^x + c

2. ## Re: integration help!

To be honest that doesn't look like an integral that could be given to a 2U student without first prompting them to differentiate $x^2e^x$. I might be missing something but I don't see how you could do that using only 2U methods.

3. ## Re: integration help!

it's actually the second part of a question,
it originally asked us to differentiate x^2e^x
and then hence find ∫x(x+2)e^x dx , i knew the answer should be x^2e^x because that was basically given to us in the first part, but getting to it was what i was stuck with.
but thank you

Oh. Just expand the integrand then.

You'll get $x^2e^x + 2xe^x$, and then the integration should be easy.

Well anyway
My wrking is not 2u but if u r interested in the working out here it is :

hey, what textbook did you get this question from
