To find :

The value of the expression

Solution :

Step 1 of 2 :

Write down the given expression

The given expression is

(x + y)²

Step 2 of 2 :

Find the value of the expression

$\sf {(x + y)}^{2}$

$\sf = (x + y)(x + y)$

$\sf = x(x + y) + y(x + y)$

$\sf = {x}^{2} + xy + xy + {y}^{2}$

$\sf = {x}^{2} + 2xy + {y}^{2}$

Thus we get

$\sf {(x + y)}^{2} = {x}^{2} + 2xy + {y}^{2}$
