You can put this solution on YOUR website! Find all numbers for which the rational expression is not defined:
2x - 7 / x2 + 5x - 24
------
The denominator cannot be zero.
----
Solve x^2+5x-24 = 0
Factor:
(x+8)(x-3) = 0
x = -9 or x = 3
----
Those are the values for which the rational expression is not defined.
