Imagine the degree of numerator is equal to that of the denominator, and that one of the expression or factors in the denominator is (x-5).

Try something simple, . Seeing the way the denominator is chosen, x=5 will be a vertical asymptote. This will NOT give the horizontal asymptote wanted; so try a change.

Still the same x=5 vertical asymptote. Also there is now x=0 vertical asymptote. Note what would happen as x is increased without bound... The x in numerator and denominator would cancel as 1, and the x-5 in numerator and denominator would cancel as 1, and the expression would approach (1/2), being as horizontal asymptote.
