Assuming we are looking for two numbers here:
1. x * y = -160
2. x + y = 36
Rewriting 2. gives
3. y = -x + 36
Substituting 3. into 1 gives:
x * (-x + 36) = -160
-x2 + 36x = -160
-x2 + 36x + 160 = 0
(x + 4) (-x + 40) = 0
x + 4 = 0
x = -4
and
-x + 40 = 0
x = 40
Therefore the two numbers are -4 & 40.

The factor pairs of 36 are (36, 1) (18, 2) (12, 3) (9, 4) (6, 6) None of them add up to 9. If that was -36, you could use 12 and -3
6*1
It is: -6 and -6
