Assume that the two numbers are represented by 'x' and 'y':
x+y=7 and xy= -120
As x+y=7, re-arrange the formula so that x=7-y
Now substitute for x: (7-y)y = -120
7y-y2= -120
7y-y2+120 = 0
y2_7y-120 = 0
(y-15)(y+8) = 0
Therefore y = 15 or -8, and so putting back into the original equation, when y=15,
x = -8, and when y= -8, x = 15
