Step 1.1

Factor out $i^{2}$ .

$i^{2} \cdot i + i^{2} \cdot 0$

Step 1.2

Rewrite $i^{2}$ as $- 1$ .

$- 1 \cdot i + i^{2} \cdot 0$

Step 1.3

Rewrite $- 1 i$ as $- i$ .

$- i + i^{2} \cdot 0$

Step 1.4

Rewrite $i^{2}$ as $- 1$ .

$- i - 1 \cdot 0$

Step 1.5

Multiply $- 1$ by $0$ .

$- i + 0$

$- i + 0$

Step 2

Add $- i$ and $0$ .

$- i$
