What is the conjugate of a polynomial?
- As has been pointed out in the comments, the conjugate of a polynomial has different meanings, depending on the context. In the expression the quantity q ( x) ¯ is the complex conjugate of q ( x), i.e., the complex conjugate of the number that you obtain by evaluating p at x. Note that x ? R, which we shall assume in the following.
