Check the answer(s) to make sure there isn't an extraneous solution.
For this case we must factor the following expression:

We rewrite the middle term as a sum of two terms whose product is

And whose sum is

These numbers are:
-5 and -3
So:

We factor the maximum common denominator of each group:
We take common factor

Answer:

Answer: it’s B
