    first factor out x\[\implies x(x^2 -5x + 6)\] now factor out the trinomial \[\implies x(x-3)(x-2)\] do you know how to get the roots now?

    @lggy, you forgot to set f(x) = 0 first.

    anyway... if you have something like \[x(x+2)(x-5)(x+4)\] then the roots will be 0, -2, 5, -5 so what do you think will be the roots of \[x(x-3)(x-2)\]

    typo...that should be "then the roots will be 0,-2,5,-4
