The difference of squares is:
(x+i√3)(x-i√3)
So the correct option is the last one, D.
<h3>Which expression gives x^2 + 3?</h3>For a complex number:
We define the complex conjugate of Z as:
Such that the product between the complex number and its complex conjugate gives:
Now, of you look at option D, you can see we have the product of a number and its conjugate, then we can write the product and use the above rule to get:
Which is what we wanted to get, so that is the correct option.
