Answer 1

Have you studied rational root theorem ?

Answer 2

well Im not sure I missed a lesson in class and I'm cramming to get in some missing homework. I'm sure if you told me or reminded me what it looked like I could figure it out

Answer 3

here

this should help

Answer 4

okay no i still don't get it

Answer 5

can you at lest tell what the constant and the leading coefficient are? I looked it up and I think I understand but I don't know those two things


Actually is the leading coefficient 2? or 8?

Answer 6

nvm ii figured it out
