 Question 30547: (18) Use the factor theorem t determin which of th following is not a factor of f(x)=3x^4-x^3-68x^2+76x+80 Thanks! Possible answers: (A) x-2 (B) 3x+2 (C) 3x-2 (D) x+5Answer 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. jon.
