The additive inverse of something is basically the opposite of it. Another way to say this is that when you add the additive inverse to -2 + 8i, it will equal 0.
An example:
The additive inverse of 7 is -7 because not only is it the opposite, but also when you add 7 and -7, it equals 0.
To solve
So all you need to do is find the opposite of -2 + 8i. You can write it as:
-(-2 + 8i) With the negative in the front because we want to find the opposite.
This then equals:
2 – 8i
You can check your answer by adding -2 + 8i and 2 – 8i to see if it equals 0:
(-2 + 8i) + (2 – 8i) → and it does equal 0
ANSWER: 2 – 8i
