Which numbers can be written as the difference between two square numbers?
Since a – b = 1, b = a-1, so b = \frac{p+1}{2} – 1 = \frac{p-1}{2}. Thus, any odd prime can be written as the difference of two squares. Any square number n can also be written as the difference of two squares, by taking a = \sqrt{n} and b = 0.
Which is the difference of two squares?
When an expression can be viewed as the difference of two perfect squares, i.e. a²-b², then we can factor it as (a+b)(a-b). For example, x²-25 can be factored as (x+5)(x-5). This method is based on the pattern (a+b)(a-b)=a²-b², which can be verified by expanding the parentheses in (a+b)(a-b).
