How do I solve the absolute value of: (x2)>1? I am completely lost and my homework online is saying I did it wrong. I came up with 3<x<1. Help!

Intermediate algebra, concepts and graphs 
Reiny,
x2>1
+(x2) > 1 or (x2) > 1
x2 > 1 or x + 2 >1
x > 3 or x < 1
the key word here is OR
and you forgot to reverse the inequality sign for one of the cases
