Quadratic Inequalities: One Variable

This lesson introduces the concept of quadratic inequalities. Using a method that involves swapping out the inequality symbol for an equal sign, students are encouraged to choose the T-method, Quadratic Formula, or Perfect Square method to find the zeroes (solutions) of the inequality. Students are encouraged to graph the quadratic inequality as an equation first, and then determine the answer to the original inequation and write the solution set as a domain.

Learning Goals:

  • To be able to find the solution set of a quadratic inequality in one variable
