Introduction

The Pythagorean theorem is a fundamental concept in geometry and trigonometry, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This theorem is often expressed as $a^2 + b^2 = c^2$, where $a$ and $b$ are the lengths of the two sides that form the right angle, and $c$ is the length of the hypotenuse. However, there is another identity that is closely related to the Pythagorean theorem, which is $\left(x^2-y2\right)^2+(2xy)2=\left(x^2+y2\right)^2$. This identity can be used to find the missing $x$- and $y$-values and Pythagorean triples.

Understanding the Identity

The identity $\left(x^2-y2\right)^2+(2xy)2=\left(x^2+y2\right)^2$ can be expanded and simplified to obtain a more familiar form. By expanding the left-hand side of the equation, we get:

$$\left(x^2-y^2\right)^2+(2xy)^2 = \left(x^4-2x^2y^2+y^4\right) + \left(4x^2y^2\right)$$

Simplifying the expression further, we get:

$$\left(x^4-2x^2y^2+y^4\right) + \left(4x^2y^2\right) = x^4 + 2x^2y^2 + y^4$$

This expression can be rewritten as:

$$\left(x^2+y^2\right)^2 = x^4 + 2x^2y^2 + y^4$$

Finding the Missing $x$- and $y$-values

To find the missing $x$- and $y$-values, we can use the identity $\left(x^2-y2\right)^2+(2xy)2=\left(x^2+y2\right)^2$. Let's assume that we have a Pythagorean triple $(a, b, c)$, where $a$ and $b$ are the lengths of the two sides that form the right angle, and $c$ is the length of the hypotenuse. We can substitute $a$ and $b$ into the identity to obtain:

$$\left(a^2-b^2\right)^2+(2ab)^2=\left(a^2+b^2\right)^2$$

Expanding and simplifying the equation, we get:

$$\left(a^4-2a^2b^2+b^4\right) + \left(4a^2b^2\right) = a^4 + 2a^2b^2 + b^4$$

Simplifying the expression further, we get:

$$a^4-2a^2b^2+b^4+4a^2b^2 = a^4 + 2a^2b^2 + b^4$$

Cancelling out the common terms, we get:

$$a^4+b^4 = a^4 + 2a^2b^2 + b^4$$

Subtracting $a^4$ and $b^4$ from both sides of the equation, we get:

$$0 = 2a^2b^2$$

Dividing both sides of the equation by $2a^2b2$, we get:

$$0 = 1$$

This is a contradiction, which means that the assumption that we have a Pythagorean triple $(a, b, c)$ is incorrect. Therefore, we need to find the missing $x$- and $y$-values.

Finding the Pythagorean Triples

To find the Pythagorean triples, we can use the identity $\left(x^2-y2\right)^2+(2xy)2=\left(x^2+y2\right)^2$. Let's assume that we have a Pythagorean triple $(a, b, c)$, where $a$ and $b$ are the lengths of the two sides that form the right angle, and $c$ is the length of the hypotenuse. We can substitute $a$ and $b$ into the identity to obtain:

$$\left(a^2-b^2\right)^2+(2ab)^2=\left(a^2+b^2\right)^2$$

Expanding and simplifying the equation, we get:

$$\left(a^4-2a^2b^2+b^4\right) + \left(4a^2b^2\right) = a^4 + 2a^2b^2 + b^4$$

Simplifying the expression further, we get:

$$a^4-2a^2b^2+b^4+4a^2b^2 = a^4 + 2a^2b^2 + b^4$$

Cancelling out the common terms, we get:

$$a^4+b^4 = a^4 + 2a^2b^2 + b^4$$

Subtracting $a^4$ and $b^4$ from both sides of the equation, we get:

$$0 = 2a^2b^2$$

Dividing both sides of the equation by $2a^2b2$, we get:

$$0 = 1$$

This is a contradiction, which means that the assumption that we have a Pythagorean triple $(a, b, c)$ is incorrect. Therefore, we need to find the Pythagorean triples.

Finding the Pythagorean Triples using the Identity

To find the Pythagorean triples using the identity $\left(x^2-y2\right)^2+(2xy)2=\left(x^2+y2\right)^2$, we can substitute $x$ and $y$ into the identity to obtain:

$$\left(x^2-y^2\right)^2+(2xy)^2=\left(x^2+y^2\right)^2$$

Expanding and simplifying the equation, we get:

$$\left(x^4-2x^2y^2+y^4\right) + \left(4x^2y^2\right) = x^4 + 2x^2y^2 + y^4$$

Simplifying the expression further, we get:

$$x^4-2x^2y^2+y^4+4x^2y^2 = x^4 + 2x^2y^2 + y^4$$

Cancelling out the common terms, we get:

$$x^4+y^4 = x^4 + 2x^2y^2 + y^4$$

Subtracting $x^4$ and $y^4$ from both sides of the equation, we get:

$$0 = 2x^2y^2$$

Dividing both sides of the equation by $2x^2y2$, we get:

$$0 = 1$$

This is a contradiction, which means that the assumption that we have a Pythagorean triple $(x, y, z)$ is incorrect. Therefore, we need to find the Pythagorean triples.
