In short, one usually uses the rational roots theorem to determine possible rational roots. the theorem can give a long list of possible roots, but that list of complete for rational roots. After those are tested, one must use other methods.

@nikkimae , for this example, you want to factor out all common factors first. You can reduce the expression into: 4B(4B^3+2B+5)

what do you do after you have reduce the expression?

You are attempting to simply the expression into factors. YOu do not multiply after  the whole point of factoring is to "undo" the multiplying.
