x+2=0 is for vertical asymptote which is x=-2

in order to find horizontal asymptote with much easier way is to use long division of polynomial

after u done with your long division

your answer should be y=x-2...

so y=x-2 is your horizontal asymptote or slant asymptote

***take note:it'll be not a straight horizontal line***
