QUADRATIC INEQUALITIESDefinition Quadratic inequalities in one variable are
inequalities which can be written in one of where a, b and c are real numbers. Procedure Solving Quadratic Inequalities 1. Move all terms to one side. Example 1 Solve the inequality, x^2 > x + 2 . Solution The corresponding equation is (x - 2)(x + 1) = 0 so… Now we test one point in each region.
So the solution to this inequality is x < -1 or x > 2. Example 2 Solve the inequality, Solution The corresponding equation is (x - 1)(x - 5) = 0 so… Now we check one point in each region.
So the solution to this inequality is 1 ≤ x ≤ 5. §4-2 PROBLEM SETSolve each quadratic inequality, and graph the solution on a number line. §4-2 PROBLEM SOLUTIONS |
