Talkin’ 2×2=5 Blues

Are we allowed to do talkin’ blues algebra proofs?

2x2=5_01-www_MarekBennett_com 2x2=5_02-www_MarekBennett_com 2x2=5_03-www_MarekBennett_com 2x2=5_04-www_MarekBennett_com2x2=5_05-www_MarekBennett_com 2x2=5_06-www_MarekBennett_com

Can you spot it?

ALSO, if YOU can come up with a better rhyme for “polynomial expansion”, we’re all ears.

And while we’re at it, by the way, here are some references that crept in on page one:
