First let's factor F(x): F(x) will be zero if any of these factors are zero. If x = 0 then the first factor is zero. If x = +-3i, then the second factor is zero. If x = -2, then the third factor will be zero. If x = 2 then the fourth factor will be zero. So 0, +-3i and +-2 are all roots of F(x) So +-3 (option (c)) are not roots of F(x).
