Answer:

Explanation:

Use the distributive property to get rid of the brackets.

9i + 2*7 + 2*3i Use the multiplication property to simplify the imaginary terms

9i + 2*3i + 2*7 Do the same to the real term

9i + 6i + 14 Use the addition of like terms property

15i + 14 And that's your answer.

You may not like my terminology, but you have to remember that every text teaches this differently.
