Understanding Quadratic Inequalities
Quadratic inequalities involve expressions of the form ax² + bx + c > 0 or ax² + bx + c < 0. Solving these inequalities requires finding the values of x that satisfy the inequality.
Steps to Solve Quadratic Inequalities
- Find the roots of the corresponding quadratic equation ax² + bx + c = 0.
- Determine the intervals using these roots.
- Test values from these intervals to determine which satisfy the original inequality.
