You can put this solution on YOUR website!
Determine the value(s) of x so that each rational expression is undefined.
(X^2-4)/(x^2+3x-10)
----------------------------
Factor where you can:
= [(x-2)(x+2)]/[(x+5)(x-2)]
-----
Undefined for x = -5 and for x = 2
------
Vertical asymptote at x = -5
Hole at x = 2
