WebSo, Area of square of length (a+b) = (a+b) 2 = (i) + (ii) + (iii) + (iv) Therefore : (a+b) 2 = a 2 + ba + ba +b 2. i.e. (a+b)2 = a2 + 2ab + b2. Hence Proved. This simple formula is also used in proving The Pythagoras Theorem. Pythagoras Theorem is one of the first proof in Mathematics. In my view, in mathematics when a generalized formula has ... WebIt is basically an algebraic expression and also a binomial. The square of this expression is written as ( a − b) 2 in mathematical form and it is expanded as a 2 − 2 a b + b 2 …
