Step 1.1

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

$- 18 \cdot - 1 - 4 i - 2 i^{2} + 5 + 10 i$

Step 1.2

Multiply $- 18$ by $- 1$ .

$18 - 4 i - 2 i^{2} + 5 + 10 i$

Step 1.3

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

$18 - 4 i - 2 \cdot - 1 + 5 + 10 i$

Step 1.4

Multiply $- 2$ by $- 1$ .

$18 - 4 i + 2 + 5 + 10 i$

$18 - 4 i + 2 + 5 + 10 i$

Step 2

Simplify by adding terms.
