Quadratic Inequalities

The Investigation Roadmap: Phase 1: Standard Form – Expressing the inequality in the form f(x) is less than 0 or f(x) is greater than 0. Phase 2: Finding Boundary Points – Solving f(x) = 0 using factorization or the Quadratic Formula. Phase 3: Interval Analysis – Dividing the number line and selecting test values to see where f(x) is positive or negative. Phase 4: The Final Verdict – Writing the solution set in interval notation. Resource Mentioned: 📚 Exercise Set 2.7 from the Precalculus textbook.
