Could someone please help me with this?
(1) If x is a nonzero real number, is x–2 always positive, always negative, or positive or negative depending on whether x is positive or negative? Explain your answer.

then (x2) = 8 which is positive
let x = 5
then x2 = 7 which is negative,

what do you think?
