Step 3.1.1

Multiply $x$ by $x$ .

$x^{2} + x \cdot 8 + 8 x + 8 \cdot 8$

Step 3.1.2

Move $8$ to the left of $x$ .

$x^{2} + 8 \cdot x + 8 x + 8 \cdot 8$

Step 3.1.3

Multiply $8$ by $8$ .

$x^{2} + 8 x + 8 x + 64$

$x^{2} + 8 x + 8 x + 64$

Step 3.2

Add $8 x$ and $8 x$ .

$x^{2} + 16 x + 64$

$x^{2} + 16 x + 64$
