Hello everyone, I wanted to get some more help with integrals.
Specifically, I had a question about the following integral.

I had also done some work relating to the expression as well, listed below.

I had done some work leading up to the final expression, but I got stuck.
I was wanting to express the integral as either ((x squared) over 2) times arctangent squared, or ((x squared) over 2) plus arctangent squared.
What's the right step forward in this case?
