Answer:


a-√(b)

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+√(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-√(b)

Therefore, the answer that completes the given statement is


a-√(b)
