To simplify the expression (9-z^2)/(2z^2+z-15), we can factor the numerator and denominator. The numerator can be factored as (3+z)(3-z), and the denominator can be factored as (2z-5)(z+3).

Now, we can cancel out the common factors between the numerator and denominator. The (3-z) terms cancel out, leaving us with (3+z)/(2z-5).

Therefore, the simplified form of (9-z^2)/(2z^2+z-15) is (3+z)/(2z-5).
