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

Question

Reiny · Answer

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 - (2y-3)^2

Pat, reread what Professor Reiny wrote you. Then read it aloud. He answered your question with questions.
