Can You Successfully Factorize x^2+y^2+z^2-2xy-2yz-2zx?

In summary, the "Factorization Challenge" is a mathematical problem-solving activity that involves breaking down a number into its prime factors. Factorization is the process of finding all the numbers that can evenly divide into a given number, and it is important in fields such as cryptography, number theory, and algebra. The goal of the challenge is to find the prime factors of a number in the shortest amount of time and with the fewest steps, making it a fun and challenging way to improve factorization skills. Regular practice and utilizing techniques such as trial division, factorization using a factor tree, or a calculator can help improve factorization skills. Participation in the "Factorization Challenge" can also be beneficial in improving skills.

My attempt:

In order to perform the factorization, I must require: $y,z \ge 0$.

\[x^2+y^2+z^2-2xy-2zx-2yz \\\\= (x-y-z)^2-4yz \\\\=(x-y-z+2\sqrt{yz})(x-y-z-2\sqrt{yz}) \\\\=(x-((\sqrt{y})^2+(\sqrt{z})^2-2\sqrt{yz}))(x-((\sqrt{y})^2+(\sqrt{z})^2+2\sqrt{yz})) \\\\=(x-(\sqrt{y}-\sqrt{z})^2)(x-(\sqrt{y}+\sqrt{z})^2)\]

Very Well done, lfdahl! (Cool)
