(x + 4) and (x - 1)
Step-by-step explanation:
x² + 3x - 4
You want to look for what numbers can be multiplied in order to get the 3rd number (the -4) that can also add/subtract to the middle number (the 3)
simply,
(4)(-1) = -4
(4) -1 = 3
to make sure you can also reverse it and if you get to the same thing that you started with it is correct.
