How do you determine if a polynomial is the difference of two squares?

Is the first term a square?
is the last term a square?
Is there a 'minus' sign between them?
e.g. 25x^2  16
e.g. (x+3)^2  (2y3)^2

This is the only information given. Sorry there isn't more, thank you for helping. 
Pat, reread what Professor Reiny wrote you. Then read it aloud. He answered your question with questions.

Oh sorry I will do that right now. Thank you.
