You're basically looking for 2 numbers that add to -7 and multiply to -8. So you could have 1,8 (1*8=8 1+8=9) -1,8 ((-1)8=-8 8-1=7) etc. You would continue this until you have the right combo. So you could factor it to
If you were to foil it, you would get
Which is our original problem and this verifies our answer.
