Best ResponseYou've already chosen the best response.0The possible answers do not make sense to me. RZT: All possible numbers of the form c/d, where c and d are integers. c must divide evenly into the constant term 8. d must divide evenly into the leading coefficient 2.

Best ResponseYou've already chosen the best response.0p is a factor of 8 and q is a factor of 2 p can be +1, +2, +4, +8 q can be +1, +2 All possibilities are all combinations of p/q

Best ResponseYou've already chosen the best response.0Using WA instead of the RZT seems not a good idea to me. It is required to give a list of POSSIBLE rational zeroes. Whether or not the formula can be factored is irrelevant.
