That's like saying that using 5 + 5 instead of 10 is "new".

How did you arrived at this formula? Maybe that's interesting... For example, could you arrive at a formula for (x+2)² or (x1)² using the same reasoning? And if so, how would you write the general formula (x+y)²? Also, look at other interesting formulas that involves products like that! For example: The product x*(x+1) is equal to x²+x, that can be show to be the sum of the first n even numbers: 3²+3 = 2 + 4 + 6 12 = 12 The numbers on the form x²1 can be shown to be written as the product (x1)(x+1). That fact alone can be used to shown that every positive number greater than two of the form x²1 is a composite number: 63 = 641 = (81)(8+1) = 7*9 What you discovered isn't new, but it can become a nice exercice! Try to apply the basic properties of real numbers and you won't have problems solving all this...
