What is the vertical asymptote(s) for y =(x-5)/(x^2-4x-12)

please help i dont know the vertical asymptote. thanks

Vertical asymptotes are vertical lines which correspond to the zeroes of the denominator of a rational function. According with the statement, let's factor the denominator:

x^2 - 4x - 12 = (x - 6) (x + 2)

Then,

Vertical Asymptotes are: x = 6 & x = - 2
