Step-by-step explanation:

Answer 2

Answer:$-36 + 48i+ 48i^{2}$

Step-by-step explanation:

1. Multiply -9 * 4 to get -36

2. Multiply -9 * -8i to get 72i

3. Multiply -6i * 4 to get -24i

4. Multiple -6i * -8i to get $48i^{2}$

5. Combine terms to ger -36 + 72i - 24i + $48i^{2}$

6. Combine like terms (72i and -24i) to get final answer:

$-36 + 48i+ 48i^{2}$
