Its not correct because ( A + b ) 2 = A 2 + b 2 + 2 A b (A+b)^2=A^2+b^2+2Ab but the given data is ( A + b ) 2 = A 2 + b 2 + 2 a b (A+b)^2=A^2+b^2+2ab can you feel the difference?

Subbu the question is slightly controversial as there is a possibility of it being correct if and only if a = A. So, I mean to say that the given equation in the question can be true, if not for all cases at least for the case of a=A. Please edit your question.
