Answer:

a-\sqrt{b}

Step-by-step explanation:

It's important to know that where roots of a polynomial involves radical roots, it does as conjugates. That is, the roots have the same terms but with a opposite middle sign between.

So, in this case, we have one root a+\sqrt{b}, which involves a root and a positive sign. To complete the conjugate behaviour, the other roots has to have the same terms but with different sign between, that is a-\sqrt{b}

Therefore, the answer that completes the given statement is

a-\sqrt{b}
