Simplify: (x + y)(x + y)

A. x2 + 2xy + y2
B. x2 + y2
C. 2x2 + 2xy + 2y2
D. x2 – y

Which one is the answer?

Answer :

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.
