Answer 2

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

$a-\sqrt{b}$
