Step-by-step explanation:
If the triangle is right then the square of the longest side (hypotenuse) will equal the sum of the squares of the other 2 sides.
longest side is x² + 1, then
(x² + 1)² =
+ 2x² + 1
The sum of the square of the other 2 sides
(x² - 1)² + (2x)²
=
- 2x² + 1 + 4x² =
+ 2x² + 1
Hence triangle is right
