x CANNOT be the longest side (hypotenuse) since it's smaller than x + 1
Therefore, using x + 1 as hypotenuse, you'll get the following equation:, and the pythagorean triple: 5-12-13.
Using 5 as the hypotenuse, you'll get the following equation:, and the pythagorean triple: 3-4-5, when the POSITIVE (> 0) value of x is chosen.
