Let one of the numbers be X
and the other be X+2
(X+2)×X = 360
X^2 + 2X = 360
X^2 + 2X - 360 =0
[splitting the middle term]
X^2 + 20X - 18X - 360 =0
X (X+20) - 18 (X+ 20)
(X-18)(X+20)
X= 18 ,(-20)
...............................
So the numbers are 18,20
Or in othercase (-20),(-18)
THERE exists two assumptions
