Answer
$\frac{(d + 3)(d - 1)}{(d + 2)(d - 3)}$
Work Step by Step
First, we want to cancel out the factors that are common in the numerators and denominators of each rational expression:
$\frac{d + 3}{d + 2} • \frac{d - 1}{d - 3}$
To multiply two expressions, we multiply the two expressions together:
$\frac{(d + 3)(d - 1)}{(d + 2)(d - 3)}$
We can keep the simplified expression in this form.
