if you were to multiply the numerator..... since it has 2 factors... what degree of a polynomial would it be you think?

anonymous · Answer

The vertical asymptotes are given by the zeros of the denominator in the rational function. Hence, look for the zeros of $$x^2-4=0$$

oh   ahemm... I read "oblique"   hmm, pretty sure that's what it said.. anyhow
