Understanding Quadratic Inequalities

A quadratic inequality is an inequality that involves a quadratic polynomial. It is in the form of ax² + bx + c > 0, ax² + bx + c < 0, ax² + bx + c ≥ 0, or ax² + bx + c ≤ 0, where a, b, and c are real numbers and a ≠ 0.

How to Use This Solver:

  • Enter your inequality in the input field provided, following the format ax^2 + bx + c [>, <, >=, <=] 0.
  • Click the "Calculate" button to solve the inequality.
  • The solution set will be displayed, and a graphical visualization of the quadratic function will appear below.
  • Use the "Reset" button to clear the input and output fields.
  • Click the copy icon to copy the solution set to your clipboard.

This tool helps you find the range of x values for which the quadratic function satisfies the given inequality. The visualization provides a graphical representation of the parabola and the solution area.
