See here: How many numbers below $100$ can be expressed as a difference of two perfect squares in only one way? One pair of numbers that can be expressed as the difference of two squares are 25 and 16: 25–16 = 9 or 5^2–4^2 = 3^2. One pair is 25 and 16 and the other pair is 25 and 9.
Which numbers cannot be written as the difference of two squared integers?
Numbers that cannot be written as the difference of two squared integers are all numbers that can be written as 2 x (any product of odd primes). Because they cannot be written as the product of two even or two odd integers.
How do you express n as a difference of 2 squares?
Thus the number of ways of expressing n as a difference of 2 squares is precisely the same as the number of divisors d of n such that d ≤ n and d and n / d have the same parity. In particular, if n is divisible by 2 but not by 4, there is no representation of n. Look first at the case n odd.
