These are all very basic but ive been studying for 8 hours straight and can't think anymore.
Please simplify:

3ab
(over)
6a^2b-12ab^2

12a^3-9a^2
(Over)
2a^2b-15ab

5-5x
(Over)
x^2-1

If you can also show your steps i would love you forever. I cant offer FG because i just got back onto this site and dont have any.
