Let me ask you a question: does x^2>4 mean x>2 or x>-2? What does x>2 or x>-2 even mean?

x^2>4 --> |x|>2 --> x>2 or x<-2.

This conclusion is based on below logic.

x^2=25 has TWO solutions, +5 and -5 so I thought

x^2>4 would also have two solutions +2 & -2, this is how I got

x>2 or

I am asking very basic question but I know only after getting my basics clear, I will be able to get good score.... Thanks for bearing with me and my stupid questions
