∙ 9y agoThe factor pairs of -138 are (138,-1)(69,-2)(46,-3)(23,-6)(-138,1)(-69,2)(-46,3)(-23,6)
None of them add up to -23. If you were just using factors of -138, you could use -46 and 23.
__________________________________________
Assume the two numbers are x and y, then
xy = -138. .............. 1
x + y = -23. ...............2
From eq 1
y = -138/x ............... 3
Substitute in eq 2;
x + -138/x = -23
Or
x2 +23x -138 = 0
Solve for x and then substitute in 3 to get y.
