If it has two perfect squares with a minus sign between them.
It is in the form aČ - bČ
A "perfect square" has a perfect square root.
Examples of perfect squares are:
9, 25, x^2, 16z^6, etc......for the variables, perfect squares have even exponents.

It has the pattern:
In fact, neither of the terms absolutely has to be a perfect square. For example,
can be factored as the difference of two squares if you simply recall that 2 is nothing more than the square root of 2 squared, hence:
\left(x\ -\ \sqrt{2}\right))
So any two term polynomial where the signs on the terms are opposite is, indeed, the difference of two squares.
