Thanks!
Let me give you a hint, in general what is for a function ?
But what if it is not that simple that u'(x) is featured so perfectly on the left. For example what if they don't match up and you get something like
Then I can't use that kind of reasoning can i?
Well, in that case you need to try other methods--sometimes they aren't expressible in elementary terms (i.e. ). But, for this one it is that case, so it is that simple.

That requires a completely different approach.
You need integration by parts. That should come in about four additional sections in your textbook. Look it up.
ok so this is one of the erf functions then right? But how do i combine it with doing integration by parts, as I think this is wrong as i ignored the (x+1) and copied the way the textbook example did a simpler example i.e.:

Either you copied incorrectly or your textbook means something else.
