## Calculus (3rd Edition)

$(-\infty, -\sqrt 3)$ U $(\sqrt 3, \infty)$
1.) Set the inequality equal to what it originally equaled, and then set it equal to the opposite sign of that number with the opposite inequality sign: $x^{2}-1 2$ 2.) Solve the first inequality for x: $x^{2}3$ $x>±\sqrt 3$ 5.) Identify the interval of x values for the inequality: $(-\infty, -\sqrt 3)$ U $(\sqrt 3, \infty)$ 6.)Combine the two intervals (using a union) $(-\infty, -\sqrt 3)$ U $(\sqrt 3, \infty)$
