2. Thanks, so that - does not matter, cause Im supposed to add all of them, and the answer I got was 37 which is the exact same answer in my textbook.

3. Then your question should have been
√2(√5-12√3) + √3(√8-2√30)

If they have 37 for the way you typed it, then the book is wrong. Check your typing.

Of course the "-" matters.

4. Oh Ok, so yeah the book is wrong, I checked again, and yeah that negative sign is an error in the book. That would have totally messed me up.
