We cannot see the answer. (Do you need it?)

But we can calculate with the answer.

You can see the symbolic result if you break it into two parts.

Sometimes, if the resulting expression is not too large, it can help to demand for the result to be simplified.

In case of your integral "factor" does the job.

See attached.

Unfortunately not. The integral won't show when you use "expand" instead of "factor".

And the splitting in two integrals is exactly what Alan suggested.
