Step 2.1.1

Factor $2$ out of $8$ .

$s = \frac{2 \cdot 4 - 4}{2}$

Step 2.1.2

Factor $2$ out of $- 4$ .

$s = \frac{2 \cdot 4 + 2 \cdot - 2}{2}$

Step 2.1.3

Factor $2$ out of $2 \cdot 4 + 2 \cdot - 2$ .

$s = \frac{2 \cdot (4 - 2)}{2}$

Step 2.1.4

Step 2.1.4.1

Factor $2$ out of $2$ .

$s = \frac{2 \cdot (4 - 2)}{2 (1)}$

Step 2.1.4.2

Cancel the common factor.

$s = \frac{2 \cdot (4 - 2)}{2 \cdot 1}$

Step 2.1.4.3

Rewrite the expression.

$s = \frac{4 - 2}{1}$

Step 2.1.4.4

Divide $4 - 2$ by $1$ .

$s = 4 - 2$

$s = 4 - 2$

$s = 4 - 2$

Step 2.2

Subtract $2$ from $4$ .

$s = 2$

$s = 2$
