Inequalities - Absolute Value Inequalities
www.wallace.ccfaculty.orgWe can solve absolute value inequalities much like we solved absolute value equa-tions. Our first step will be to isolate the absolute value. Next we will remove the absolute value by making a three part inequality if the absolute value is less than a number, or making an OR inequality if the absolute value is greater than a number.

www.sydney.edu.au1.3 The absolute value function Before we define the absolute value function we will review the definition of the absolute value of a number. The Absolute value of a number x is written |x| and is defined as |x| = x if x ≥ 0or|x| = −x if x<0. That is, |4| = 4 since 4 is positive, but |−2| = 2 since −2 is negative.

A Quick Algebra Review - Hood College
www.hood.eduWhen solving absolute value equations, we must consider that the number inside could have been negative before you applied the absolute value! For example: │x + 2│= 3 x + 2 and x + 2 3 -3 When we take the absolute value, both are equal to 3. So we end up with TWO SOLUTIONS for this equation. -2(x – 5) < 10 -2 -2
