do the long division ... the quotient will be a linear expression that is the equation of the slant asymptote (ignore the remainder).

here's a link with some examples ...

Slant, or Oblique, Asymptotes - Mar 21st 2009, 05:29 AMSeanBE
Did you figure out the answer? I learned about oblique/slant asymptotes a week ago and I thought I might try this problem out for practice. Would the answer by any chance be : x-4 R 4x+3 OR x-4 + (4x+3/x^2-2) Oblique asymptote being x-4 . Not sure If I am allowed to supply answers but I would just like to see if I am right.

A slant asymptote always has this form:

y=mx+n

Where :

and

In this particular case of yours you have :

So the fianl result will be :

That's all,

Have a nice day!
