i started a A level maths course and have a big half way test and would like some pointers in the right direction please thank you for any help

(x-y)(1+1)

x y

on this question do i find a common donominator so i get y over xy +x over xy so i would have (x-y)(y+x) then multiply out from here ?

next question

(2p-3q)^2 + (2p-3q)

so i get to the point

4p^2-6pq-6qp+9q^2 +(2p-3q) is this it or what else do i do any help please

and last question i dont even know how to start this

m+1-m-2

2m-3 2m+3

thank you 4 any help
