(2x+3)+(x-4) doesn’t match up with the work

Should be (2x+3)(x-4)

MATH HW QUESTION

QUICK! I need help with some of my math homework and I have a few questions. Okay so when I'm combining likes terms how do I know whether to add or subtract when combining them? Do I base it off the sign one of the coefficients have in front of them or do I just base it on which sign is beside the first coefficient. For example here's one of my problems:

  3m + 4 - 8m - 5d - 9 - 2d - 4m

 ^So to combine 3m, 8m, and 4m how would I know which coefficient to add or subtract?

    I need a little bit explaining to this so feel free to go lengthy on an explanation, just as long as I get it. Thanks!
