You can put this solution on YOUR website!
%28x%2B2%29%2F%28x%5E2-9x%2B14%29
The big deal in math is that you are NOT allowed to divide by zero!! Therefore, any number that makes a denominator zero is NOT allowed!! In this case, the denominator factors:
%28x%2B2%29%2F%28%28x-7%29%28x-2%29%29

Therefore the values of x that must be excluded are x=7 and x=2.
