(a+b)^2=a^2+2ab+b^2 is one of the elementary formula thought in high school mathematics. Almost every one of you knew this formula and applied while solving mathematical problems during school days. But did ever wonder why (a+b)^2=a^2+2ab+b^2? Why not (a+b)^2=a^2+b or something else?

In this video Khurshed Batliwala, a gold medallist in Mathematics from IIT, Bombay explains this formula in very simple terms and makes you wonder how easy mathematics is when we understand the concepts behind them.

If you are student it’s a must watch video and if you have kids studying elementary school it’s must to show it them.
