Question

I need help on #3!!!

Answer 1

`\frac{{x}^(2) - 9}{{x}^(2) - 16}`

Explanation:

`[((x - 3)(2x + 1))/((x - 4)(x + 5))][((x + 3)(x + 5))/((x + 4)(2x + 1))] = ((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.
