which of the following are possible rational roots of the polynomial function

Question

F(x)=3x²-3x+5

 

Answer 1

You supply no list for "which of the following" possible rational roots.  In any event, since the discriminant is (-3)²-4(3)(5) = 9 - 60 = -51, there are NO Real roots for the equation F(x) = 0.
