According to the rational root theorem, potential rational roots must be in the form of a/b, where a is a factor of the constant term and b is a factor of the leading coefficient. Is 3 a factor of 28 and 4 a factor of 36? Does it satisfy the rational root theorem? Substituting in for x does not result in 0. The remainder is not 0 when dividing by 3.
1) Yes
2) No
