  2. Identify what the absolute value inequality is set “equal” to… a. If the absolute value is less than zero , there is no solution. b. If the absolute value is less than or equal to zero , there is one solution . Just set the argument equal to zero and solve. c. If the absolute value is greater than or equal to zero , the solution is all

  You can solve a compound inequality by solving two inequalities separately. When a compound inequality with “and” is written as a single inequality, you can solve the inequality by performing the same operation on each expression. Solving Compound Inequalities with “And” Solve each inequality. Graph each solution. a. −4 < x − 2 < 3 b.

  Solve the compound inequality and graph the solutions. 8 < 3x – 1 ≤ 11 8 < 3x – 1 ≤ 11 +1 +1 +1 9 < 3x ≤ 12 3 < x ≤ 4 Since 1 is subtracted from 3x, add 1 to each part of the inequality. Since x is multiplied by 3, divide each part of the inequality by 3 to undo the multiplication. The solution set is {x:3 < x ≤ 4}.

  Figure 3. A number line showing x ≤ 2. Example Suppose we wish to solve the inequality −2x > 4. In order to solve this we are going to divide both sides by −2, and we need to remember that because we are dividing by a negative number we must reverse the inequality. x < −2 There is often more than one way to solve an inequality.

  The inequality symbols , and ≥ are used to compare two numbers and to denote subsets of real numbers. For instance, the simple inequality x ≥ 3 denotes all real numbers x that are greater than or equal to 3 As with an equation, you solve an inequality in the variable x by finding all values of x for which the inequality is true.

  Example: A Quadratic Inequality Solve the inequality x2 + 3 4x. First we move all of the terms to one side: x2 4x+ 3 0 We then factor the non-zero side: (x 3)(x 1) 0 The expression on the left can only change sign if one of the factors changes sign. This happens (for a linear factor ) when the factor is zero.

Thus, we assume that x ≤ 2. We now reason as follows1: x ≥ √ 2−x x2 ≥ 2−x (We squared both sides1) x2 +x−2 ≥ 0 (I3) (x−1)(x+2) ≥ 0 ...

  Solve the inequality x(x – 1)2(x – 3) < 0 All nonzero terms are already on one side of the inequality. Also, the nonzero side of the inequality is already factored. So we begin by finding the intervals for this inequality.
