Answer 1

For any natural number m > 1, 2m, m² − 1, m² + 1 forms a Pythagorean triplet.

If we take m² + 1 = 6, then m² = 5

The value of m will not be an integer.

If we take m² − 1 = 6, then m² = 7

Again the value of m is not an integer.

Let 2m = 6

m = 3

Therefore, the Pythagorean triplets are 2 × 3, 3² − 1, 3² + 1 or 6, 8, and 10.
