# 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.

$$2x^3-4x^2-2x+4=2x^2(2x-4)-1(2x-4)$$
