Step 1.1

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

$2 \cdot - 1 - 3 (i - 7) + 5 i$

Step 1.2

Multiply $2$ by $- 1$ .

$- 2 - 3 (i - 7) + 5 i$

Step 1.3

Apply the distributive property.

$- 2 - 3 i - 3 \cdot - 7 + 5 i$

Step 1.4

Multiply $- 3$ by $- 7$ .

$- 2 - 3 i + 21 + 5 i$

$- 2 - 3 i + 21 + 5 i$

Step 2

Simplify by adding terms.
