Answer:
B
Step-by-step explanation:
yes, we need two numbers that multiplied with each other results in -48.
that means already that one of them has to be positive and the other negative.
that gives us (with all +/- alternating sign combinations)
2 and 24
3 and 16
4 and 12
6 and 8
to pick from there we see that the "middle" term is -2x.
that means that the absolute value of the negative number has to be 2 more than the positive number (so that when adding the intermediate multiplication terms we end up with -2x).
the only choice is therefore 6 and -8.
and that makes B the right answer.
