How do you find the asymptotes for #y = (8 x^2 + x - 2)/(x^2 + x - 72)#?
This type of equation is called a rational function:
First both the numerator and denominator must be factored to see if there are any holes (when factors can be canceled from both the numerator and the denominator).
The numerator can't be factored easily unless you use the quadratic formula. This means there will not be any hole.
