A viewer suggested number theory problem (Quite Famous)

[@ivankaznacheyeu4798]

The problem was solved for integer positive numbers. For real positive numbers there is no maximum value only supremum value 992.25 which corresponds to a=b=31.5-delta,c=d=delta at delta approaching zero.

Yes ....good improvement

[@akifbaysal9141]

I thought question was max of ab+bc+ac which to my quick analysis without watching your video was 1281 (a,b,c,d =20, 21,21, 1) but when I turn to the end of your video you were finding max of something else, not ab+bc+ac.. Can you ensure your 1st screen is always good i.e. all hints are given, solution domain is cleanly expressed. I like to solve on my own without any clue or help, jus thet problem properly stated 1st..

Thanks for your suggestion I was calculating maximum of AB + BC + CA only but I am adding in subtracting something and factorizing it to make completely different form and then doing something

finally :)

Isn’t it 991.25 (both a and b are 30.5)

[@Mathematica1997]

Maybe but we have to work out and check
