## QUADRATIC INEQUALITIES
where a, b and c are real numbers.
1. Move all terms to one side.
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.
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 |
