Answer:

\frac{{x}^{2} - 9}{{x}^{2} - 16}

Step-by-step explanation:

[\frac{(x - 3)(2x + 1)}{(x - 4)(x + 5)}][\frac{(x + 3)(x + 5)}{(x + 4)(2x + 1)}] =  \frac{(x - 3)(x + 3)}{(x - 4)(x + 4)} =  \frac{{x}^{2} - 9}{{x}^{2} - 16}

In order to figure this out, you have to factor every single trinomial in the denominators and numerators. By doing this, you will arrive at your answer alot swifter.

I am joyous to assist you anytime.
