To find where there are holes, we need to make the function =
(0)/(0).

((x-5)(x-2))/((x-2)(x+4))
If you plug in
x=2, you get
(0)/(0), which means there is a hole in the graph when
x=2

To find where there are vertical asymptotes, we need to make just the bottom 0.
Ex.
(1)/(0)

((x-5)(x-2))/((x-2)(x+4))
If you plug in
x=-4, you get
((-9)(-6))/(0) = (54)/(0), which means there is a vertical asymptote when
x=-4
