If x is a nonzero real number,is x-2 always positive,always negative,or positive or negative depending on whether x is possible or negative explain

1. Damon

if x = 4, x-2 = 2
if x = 3, x-2 = 1
if x = 2, x-2 = 0

if x = 1, x-2 = -1

if x = 0, x-2 = -2

if x = -1, x-2 = -3

so + or - depending on if x greater than or less than 2
