-a-b

Explanation:

Since every real number is a complex number with an imaginary part of color(blue)0, the given expression can be written as,

-a-b+color(blue)0i

To find the complex conjugate, negate the imaginary number, "0i," which becomes "-0i." Writing out the expression, the complex conjugate would be,

-a-b-0i

However,

-a-b+0i=-a-b-0i

Thus, the complex conjugate of "-a-b" is "-a-b" itself.
