Best ResponseYou've already chosen the best response.3\[\pm\frac{factors.of.15}{factors.of.1}\] since the last term is 15 and the first term is 1

Best ResponseYou've already chosen the best response.0would there be anything for the x? would it just be zero? bc thts the one thts confusing me

Best ResponseYou've already chosen the best response.3the actual values that will zero this out can get complicated; the question is just asking what possible values there could be to test

Best ResponseYou've already chosen the best response.3we know that whatever the actual zeros are, they have to multiply to get 15 and 1

Best ResponseYou've already chosen the best response.0so wouldn't it be ± 1, ± 3, ± 5, ± 15?

Best ResponseYou've already chosen the best response.3so, 15 factors into 1,3,5,15 and 1 factors into 1 which is trivial \[\pm{1,3,5,15}\]are our possible zeros to test out if need be
