Find all solutions of the inequality
This is a preview of coming attractions. There are no rules to apply here; in particular,
DO NOT try to divide by x. Why not?
Instead, look at the inequality again: A square of a number is always positive (or zero). Thus, it will never be less than or equal to -1.
By "close inspection", we have found out that the inequality has no solutions; the set of solutions is empty.
