$\color{blue}{-12, -6, -\sqrt{4}, 0, \text{ and } 6}$

Work Step by Step

The set of integers is: $\left\{...-3, -2, -1, 0, 1, 2, 3, ...\right\}$ The set of rational numbers contain all the numbers that can be expressed as $\dfrac{p}{q}$ where $p$ and $q$ are integers and $q \ne 0$. Note that: $-\sqrt{4} = -2$ Thus, the integers among the elements of $K$ are: $\color{blue}{-12, -6, -\sqrt{4}, 0, \text{ and } 6}$
