Step 1.1

Factor $8$ out of $8 a$ .

$\frac{8 (a) - 8 b}{b - a}$

Step 1.2

Factor $8$ out of $- 8 b$ .

$\frac{8 (a) + 8 (- b)}{b - a}$

Step 1.3

Factor $8$ out of $8 (a) + 8 (- b)$ .

$\frac{8 (a - b)}{b - a}$

$\frac{8 (a - b)}{b - a}$

Step 2

Step 2.1

Factor $- 1$ out of $a$ .

$\frac{8 (- 1 (- a) - b)}{b - a}$

Step 2.2

Factor $- 1$ out of $- b$ .

$\frac{8 (- 1 (- a) - (b))}{b - a}$

Step 2.3

Factor $- 1$ out of $- 1 (- a) - (b)$ .

$\frac{8 (- 1 (- a + b))}{b - a}$

Step 2.4

Reorder terms.

$\frac{8 (- 1 (- a + b))}{- a + b}$

Step 2.5

Cancel the common factor.

$\frac{8 (- 1 (- a + b))}{- a + b}$

Step 2.6

Divide $8 \cdot (- 1)$ by $1$ .

$8 \cdot (- 1)$

$8 \cdot (- 1)$

Step 3

Multiply $8$ by $- 1$ .

$- 8$
