Substitute this expression, is it negative or positive? Really basic fundamentals
Here is the example: https://imgur.com/a/WZwxWbh
Which is right, is it 1) or 2)? And why?
I'm forgetting really simple stuff. Trying to do an integration via parts and I got the sign wrong for one of the bits.

You need to subtract the whole of X from b, so X=(c-d)
And therefore it's number 2
Do you understand why?

2.
The clue is in what you did. Put some brackets around what you're trying to substitute for.
b-x = b - (x) = b - (c - d)
That will isolate your substitution from any sign considerations, and you can then process them when you remove the brackets.
