## Algebra 2 (1st Edition)

$x\leq-1$ or $x\gt 1$ The solutions are all real numbers that are less than or equal to $-1$ or greater than $1$. This is the part of the number line containing the numbers to the left of $-1$ (included) and to the right of $1$ (excluded). Use a solid dot to indicate $-1$ is a part of the solution and an open dot to indicate that $1$ is not.
