I have just shown you the factorisation, and then you asked why its +1 and not -1, and now you ask how it turns into -1... which it doesnt.
If you are talking about the -1 at the end of the expression on its own, then this is the same -1 I told you to ignore in my first post. We dont manipulate it at all here.

That clears things up. I was thinking about the -1 you told me ignore.
