To simplify the expression (x^2-2x-3)/(x^2-7x+12), you can factor both the numerator and the denominator.

The numerator can be factored as (x-3)(x+1), and the denominator can be factored as (x-3)(x-4).

Now, you can cancel out the common factor of (x-3) from both the numerator and the denominator.

Therefore, the simplified expression is (x+1)/(x-4).
