Find this vertical asymptote

    Alright, I know how to find the horizontal asymptotes

    but the vertical asymptotes?

    I tried dividing the polynomials but maybe I am not doing it correctly because I cannot get a normal answer...

    and I am unsure how to factor the denominator.

    [tex]2x^3-4x^2-2x+4=2x^2(2x-4)-1(2x-4)[/tex]

    does that help you?
