(adsbygoogle = window.adsbygoogle || []).push({}); perfect square???

hello everyone! i have come accross an on-going research onDETERMINING A PERFECT SQUARE GIVEN A DIFFERENCE . However, I have a feeling that this was not an original one.

the researcher used the Pythagorean theorem to arrive at his so called "theorem".

would anyone give me a reference on some related studies. thank you very much!
