$$\mathop{\operatorname{zeros}\,}\limits_{x \in S} f(x)$$
The set of values $x \in S$ satisfying $f(x) = 0$.
$$\mathop{\operatorname{zeros}\,}\limits_{x \in S,\,P(x)} f(x)$$
The set of values $x \in S$ satisfying $P(x)$ and $f(x) = 0$.
Symbolic evaluation examples
$$\mathop{\operatorname{zeros}\,}\limits_{x \in \mathbb{C},\,\operatorname{Re}(x) > 0} \left[{x}^{4} - 4 {x}^{2} + 2\right]$$$$\left\{\sqrt{2 + \sqrt{2}}, \sqrt{2 - \sqrt{2}}\right\}$$
