Question 1209131: Fill in the blank with a constant, so that the resulting expression can be factored as the product of two linear expressions:
2mn - m + 7n - ___ Answer by mccravyedwin(408) (Show Source):
2mn - m + 7n - ___
Let's try to factor it, thinking of "FOIL":
Let's try 2m and n for the "Firsts"
Then to get the 7n for the "Inners" we have to put a +7 in the right of the first parentheses.
Finally to get the -m for the "LASTS" we must put in the remaining blank.
So when you FOIL that out you get
So the term we have to add is the "OUTERS" .
[You already had a - sign, so what we'd put in the blank would be .
