Step 2.1.1

Multiply $x$ by $x$ .

$x^{2} + x y + y x + y \cdot y$

Step 2.1.2

Multiply $y$ by $y$ .

$x^{2} + x y + y x + y^{2}$

$x^{2} + x y + y x + y^{2}$

Step 2.2

Add $x y$ and $y x$ .

Step 2.2.1

Reorder $y$ and $x$ .

$x^{2} + x y + x y + y^{2}$

Step 2.2.2

Add $x y$ and $x y$ .

$x^{2} + 2 x y + y^{2}$

$x^{2} + 2 x y + y^{2}$

$x^{2} + 2 x y + y^{2}$
