Given two integers, x and y, their squares are x^2 and y^2.
The difference between them is called the difference of perfect squares and is (x^2-y^2)
This is important because we can always factor this as (x+y)(x-y).
We don't really need x and y to be integers, but in elementary algebra classes they often are. In reality, they can by any numbers.
The idea behind this is when you multiply (x+y)(x-y) the xy and -xy terms cancel each other out and you are left with the x^2 and -y^2 terms.

A perfect square in mathematics is a number that can be expressed as the square of an integer. For example, numbers like 1, 4, 9, and 16 are perfect squares because they can be written as (1^2), (2^2), (3^2), and (4^2), respectively. Perfect squares are always non-negative and have an integer square root.
