Finding the Additive Inverse

Question

What is the additive inverse of of (6-5i) ? 

 

Thank you

Answer 1

A number and its additive inverse add to 0.

 

6 - 5i + x = 0         subtract 6 from both sides

-5i + x = -6            add 5i to both sides

x = -6 + 5i

 

The additive inverse is -6 + 5i
