Understanding Quadratic Inequalities

A quadratic inequality has the form:

ax² + bx + c < 0 (or ≤, >, ≥)

Where:

  • a, b, and c are real numbers
  • a ≠ 0 (otherwise it's not quadratic)
  • The solution set is the set of all x-values that make the inequality true

Steps to Solve

  1. Find the roots of the quadratic equation
  2. Determine the direction of the parabola (upward if a > 0, downward if a < 0)
  3. Identify the regions where the inequality is satisfied
  4. Express the solution in interval notation

Applications

  • Physics problems involving projectile motion
  • Economics and business optimization
  • Engineering design constraints
