Question

for every real number x, if x²>1, then x>1. true or false?

Answer 1

just kidding false i wasnt paying attention to the second part. the first one is true because even if its negative whn multiplied by its self its going to give you a positive but if its negative then false for the second one

Answer 2

\[x²>1 \rightarrow x> \pm1\]
Therefore
Either
\[\ x> 1 \]
or x> -1
Thus x>1 is one of the solutions, which should be considered as TRUE.
