Explanation Given: The inequality is { x : | x 2 − 1 | > 2 } . Formula used: In the absolute value equation, if | a x + b | > k , where k > 0 then a x + b > k or a x + b < − k . Calculation: The inequality is { x : | x 2 − 1 | > 2 } . By the absolute value equation, if | a x + b | > k , where k > 0 then a x + b > k or a x + b < − k . | x 2 − 1 | > 2 , 2 > 0 So, x 2 − 1 > 2 and x 2 − 1 < − 2 . Solve the above inequalities. First, solve the inequality x 2 − 1 > 2 . Add 1 on both sides. x 2 − 1 + 1 > 2 + 1 Solve the above expression
