To simplify the expression (3x^2 - 9)/(x^2 + x - 2), we can factor both the numerator and the denominator. The numerator can be factored as 3(x^2 - 3), and the denominator can be factored as (x - 1)(x + 2).

Now, we can cancel out the common factors of (x^2 - 3) and (x - 1) from the numerator and denominator.

Therefore, the simplified form of (3x^2 - 9)/(x^2 + x - 2) is 3(x - 1)/(x + 2).
