3/4 lessons, includes step by step guide, worked examples, practice questions with solutions, and worksheets. The big idea is to solve the inequalities to find the critical values, the to test a point on a number line to determine the correct inequality.
To be able to solve quadratic inequalities algebraically.
The lessons are split into 3 sections:
- A recap of solving linear inequalities.
- Solving simple quadratic inequalities.
- Solving harder quadratic inequalities that involve rearranging and factorising to find the critical values.
