how to graph y= (x^23x10)/(x2)

(x5)(x+2)/(x2)
well we know it is 0 at x = 5 and at x = 2
and we know it explodes at x = 2
we know it goes to y = x as x gets +big
we know it goes to y = x as x gets big
now between those zeros at 2 and+5
lies x = 0 when y is 10/2 = 5
so that is a start :) 
I don't understand what you mean "it is 0 at x=5 and at x=2"?
