Quadratic inequalities. In these lessons we want to explain how to solve a quadratic inequality using the graph of a parabola (quadratic function). Our work is going to be done in two steps: we are going to learn how to sketch the graph of a parabola. we are going to study the sign of a quadratic polynomial using parabolas. Quadratic Function

7.6 Quadratic Inequalities. Summary 1: Quadratic inequalities in one variable are expressed in one of the following forms: 1. ax2 + bx + c > 0. 2. ax2 + bx + c 0. 3. ax2 + bx + c < 0. 4. ax2 + bx + c 0. A critical number in a quadratic inequality is a number that makes the given polynomial equal to zero.
