To simplify the expression (x^2+4x-32)/(x+5) * (x-3)/(x^2-7x+12), we can first factor the numerator and denominator of each fraction.

The numerator of the first fraction, x^2+4x-32, can be factored as (x+8)(x-4). The denominator of the first fraction, x+5, cannot be factored further.

The numerator of the second fraction, x-3, cannot be factored further. The denominator of the second fraction, x^2-7x+12, can be factored as (x-3)(x-4).

Now, we can cancel out common factors between the numerators and denominators.

(x+8)(x-4)/(x+5) * (x-3)/(x-3)(x-4)

After canceling out the common factor (x-4) and (x-3), we are left with:

(x+8)/(x+5)
