Answer 1

Answer:
`-36 + 48i+ 48i^(2)`

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)`
