-1 and -120
None of the factor pairs of 120 add up to -14. If that was -120, you could use -20 and 6.
-15+-8=-23 -15*-8=120
-6 and -20
1
you can multiply by 2, or add 120, or divide by 1/2. I'd say it's best to multiply, or find the "product."
70
-10 and 2 -12 and 4 -20 and 12
120
2x6 is 12 Add a zero (the zero from 20) and you have: 120
140
Those two numbers would be 80 and 40. 80*40=3200 80+40=120
