The integral should have the absolute value,  but for this question, your result don't need it. In your process, you can remove the absolute value because constant C can be positive, negative or 0. You can read the 8th page of the slide to see details.

For your first question, the integral should be the absolute value.
However, when you are doing such problems, I believe that you can just assume everything in the absolute value symbol is positive because you already had a constant C (except for some cases that have a restriction on the variables). Also, I think your answer is correct and well-written.
Correct me if I'm wrong!
