To simplify the expression (x^2+5x+6)/(x+1) * (x^2-1)/(x+3), we can first factor the numerator and denominator of each fraction.

The numerator of the first fraction, x^2+5x+6, can be factored as (x+2)(x+3). The denominator of the first fraction, x+1, cannot be factored further.

The numerator of the second fraction, x^2-1, can be factored as (x+1)(x-1). The denominator of the second fraction, x+3, cannot be factored further.

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

(x^2+5x+6)/(x+1) * (x^2-1)/(x+3) simplifies to [(x+2)(x+3)/(x+1)] * [(x+1)(x-1)/(x+3)].

Next, we can cancel out the common factors (x+1) and (x+3) in the numerator and denominator.

The simplified expression is (x+2)(x-1).
