Answer by longjonsilver(2297) (Show Source): You can put this solution on YOUR website!
for A) to be a factor, it means that when x=2, you will get zero for f(x).
for B) to be a factor, it means that when x=-2/3, you will get zero for f(x).
for C) to be a factor, it means that when x=2/3, you will get zero for f(x).
for D) to be a factor, it means that when x=-5, you will get zero for f(x).
So do all 4 calculations yourself :-) and find out.
