You can put this solution on YOUR website!
y= x+5/(x-2)(x-3)
y=(x+5)/(x^2-5x+6)
(graph 300x200 pixels, x from -6 to 5, y from -10 to 20, (x+5)/(x^2-5x+6) ).

y= x+5/(x-2)(x-3)
"Holes" would occur when the numerator and denominator have a common factor which is an expression which could be zero. Since this fraction has no such common factors, there will be no "holes".
Vertical asymptotes will occur for x-values which make the denominator zero. For this equation the denominator will be zero if x = 2 or x = 3. So the vertical lines, x = 2 and x = 3 will be vertical asymptotes for this equation.
Horizontal asymptotes will occur if y approaches some constant value when x-values become very large (positive or negative).
For this equation, when x-values become very large, the denominator of the fraction becomes very large. This makes the fraction very, very small. In fact the fraction approaches zero in value. So as x-values become very large, the fraction becomes negligible and the y-value approaches the value of the non-fraction portion of the right side: x.
Since x is not a constant value there will be no horizontal asymptotes. But there will be what is called a slant asymptote! The line y = x will be a slant asymptote.
