and when i do these types of problems usually i factor it out to get the asymptotes but idk how to factor the bottom. please help?

Hole when numerator is zero Hole at x = 5 Vertical asymptote when denominator is zero x^2 + 9 = 0 <<< can never = 0, so no VA Horizontal asymptotes where the limit of x > +infinity and infinity I'll draw you the work for HA

anything over infinity means it's going to 0 so HA: Y = 1
