Understanding Quadratic Inequalities

A quadratic inequality is an inequality that involves a quadratic polynomial. The standard form is ax² + bx + c < 0 (or ≤, >, ≥ 0), where a, b, and c are constants, and a ≠ 0. Solving a quadratic inequality means finding the range of values for x that satisfy the inequality. This tool helps you solve these inequalities and visualize the quadratic function, making it easier to understand the solutions graphically. By inputting the coefficients and choosing the inequality type, you can quickly find the solution range and see the corresponding graph.
