so answer is 4 and -35.You couldnt have looked very well...you need a system !qed-Factors of -140: -1,......
I'm working a math problem and I don't know if I'm just losing my mind or if my head ache is keeping me from not focusing but i'm looking for 2 numbers that multiply to get -140 and add to get -31.

Sorry for the dumb question but I'm having one of those days.

-35 and 4

look at factor pairs of 140
(1,140) with these I can make up 141 (140+1) or 139 (140-10
(2,70) will give me 72 or 68
(4,35) will give me 39 or 31
to make -31, i have to take -35 and 4 when I multiply -35x4=-140
so answer is 4 and -35.

(- 35) and (4)

You couldn't have looked very well...you need a system !
