Step 2.1.1

Move $4$ to the left of $b$ .

$4 \cdot b + b (- c) - 8 \cdot 4 - 8 (- c)$

Step 2.1.2

Rewrite using the commutative property of multiplication.

$4 b - b c - 8 \cdot 4 - 8 (- c)$

Step 2.1.3

Multiply $- 8$ by $4$ .

$4 b - b c - 32 - 8 (- c)$

Step 2.1.4

Multiply $- 1$ by $- 8$ .

$4 b - b c - 32 + 8 c$

$4 b - b c - 32 + 8 c$

Step 2.2
