4I - Solving quadratic inequations
Solving quadratic inequations is more complex than linear inequations. To solve quadratic inequalities, use the following steps:
- Solve the quadratic inequality as a regular equation.
- Graph the quadratic expression.
- Determine which interval(s) satisfy the inequality from the graph.
