-73
If we want two numbers to add to -1 then the two numbers must be of the form n and -(n+1). If we want two numbers to multiply to -72 then the two numbers must be of the form n and -m. It makes sense to look at factors of 72 which satisfy these equations. In this case, the only solution is 8 and -9.
