Question

What is conjugate of -a-b?

Answer 1

Without an indication of an imaginary term, there is no complex conjugate.

Explanation:

The complex conjugate of a real number is the real number.

So, if `a` and `b` are both real, then the complex conjugate of `-a-b` is also `-a-b`

If there is a typographic error in the question and the intended question is: "What is the complex conjugate of `-a-bi`?",

then the answer is `-a+bi`.
