Today, I learned something from a rage comic. O.O indeed
So of course I have to go into a full explanation of this.
Basically this takes a number n and claims that (at least for some restricted n) that
n^2 = 100(n-25)+(50-n)^2
I was not expecting that to work out so well. So (if I’m not mistaken) this actually works for any real number.
Of course, you have to view it as a sum and not just the digits; ie if you use 96 you get:
96-25=71; 50-96=-46; (-46*-46)=2116 (as seen in the comic)
but obviously 96^2 ≠ 712116
however, 96^2 = 9216 = 7100+2116 = 100(71)+2116
