Prove : a square + b square = ( a square + b square) - 2ab

1.	Prove : a square + b square = ( a square + b square) - 2ab
Answer» Yes it\'s correct Is this formula is correct?? To show this equation to be true, we can simply expand the left-hand side of the equation and see what we get:(a+b)2−2ab ............=(a+b)(a+b)−2ab ..........=a2+ab+ab+b2−2ab ..........=a2+2ab+b2−2ab ............=a2+b2 ..........Therefore, we have shown thata2+b2=(a+b)2−2ab ........ hope this helps uhh?
