Answer 1

Answer:

(A)$x^{2}+2xy+y^{2}$

Step-by-step explanation:

The given equation is :

$(x+y)(x+y)$

=$(x+y)^{2}$

We need to simplify the given equation, so

Using the identity,

$(a+b)^{2}=a^{2}+2ab+b^{2}$, we have

$(x+y)(x+y)$=x^{2}+2xy+y^{2}[/tex]

Which is the required simplified form of the given equation.

Hence, option A is correct.
