We know that a triangle with side lengths x2 − 1, 2x, and x2 + 1 is a right triangle. Using those side lengths, find the missing triples and x-values. Write the triples in parentheses, without spaces between the numbers, and with a comma between numbers. Write the triples in order from least to greatest.
