Question

whole square of a + b

Answer 1

Taking LHS of the identity:  

(a + b)2  

This can also be written as:  

= (a + b) (a + b)  

Multiply as we do multiplication of two binomials and we get:  

= a(a + b) + b(a + b)  

= a2 + ab + ab + b2  

Add like terms and we get:  

= a2 + 2ab + b2  

Rearrange the terms and we get:  

= a2 + b2 + 2ab  

Hence, in this way we obtain the identity i.e. (a + b)2 = a2 + b2 + 2ab

Answer 2

(a+b)2=A2+B2 +2Ab.
