Answer:
(A)[tex]x^{2}+2xy+y^{2}[/tex]
Step-by-step explanation:
The given equation is :
[tex](x+y)(x+y)[/tex]
=[tex](x+y)^{2}[/tex]
We need to simplify the given equation, so
Using the identity,
[tex](a+b)^{2}=a^{2}+2ab+b^{2}[/tex], we have
[tex](x+y)(x+y)[/tex]=x^{2}+2xy+y^{2}[/tex]
Which is the required simplified form of the given equation.
Hence, option A is correct.
