that is a big list

anonymous · Answer

LOL did you try yourself or are u lazy to do all the work?

anonymous · Answer

the idea for all of them is to factor and cancel, not actually multiply or divide
what you want to try to do is factor each polynomial and see what common factors you can cancel top and bottom
