This is quite hard; there are three terms and we must decide correctly how to group them into two different groups for the integration by parts.
I tried to put x as a solo term and everything else as a group, but when I tried integration by parts, I was led to deeper territory, so it was not a good approach.
Finally, I decided this order of grouping and as it turns out, it was a good choice.
