Which property of addition is shown below? if x = 1 + 2i and y = –1 – 2i, then x + y = 0

Additive inverse property is satisfied in the given question

Explanation:

We have been given with two complex numbers  x=1+2i and  y= -1 -2i

we can clearly see that y is additive inverse of x

Since, additive inverse of the complex number is -(a+ib)

Where a and b are real numbers

Here in given numbers a=1 and b=2i

sum of number and its additive inverse is zero.
