Answer:
B. -3(4x + 1) (x - 4)
Step-by-step explanation:
Out of the other answer choices, "B," is the only that factorizes correctly and ends up with the correct factorization (It already gives you the break-down of the trinomial).
However, if you're unsure about the answer, you can always take the end result: -3(4x + 1) (x - 4), and multiply it together to see if you can end up with the original trinomial:

For this case we must find an expression equivalent to:
To express in scientific notation we must take into account that the power will be positive, that is, the decimal is run to the right.
We test each option.
Option A:
If we run the decimal 9 spaces to the left we have:
Option B:
We discard it because the exponent is negative.
Option C:
We run the decimal 6 spaces to the right
Option D:
We run the decimal 9 spaces to the right
Answer:
Option D
