What will I learn?
This concise Quadratic Inequalities Course gives you a clear, reliable toolkit for solving and interpreting inequalities with confidence. You will review core definitions, parabola behavior, roots, and interval notation, then master factoring, completing the square, quadratic formula use, sign charts, and multiplicity. Practical word problems, templates, and common-error checks ensure accurate, well-justified solutions every time.
