QUESTION 2 2.1 What is meant by a problem-centred approach in the teaching and learning of mathematics? Give a problem in FET Mathematics and indicate the teacher's role in using a problem-centred approach. 2.2 Given is the quadratic inequality:

`3x_(2)>=-x+4`

. 2.2.1 Use the steps of Polya to solve the inequality. You must explain in detail what you are doing in each step. 2.2.2 What challenges may learners experience when solving this quadratic inequality? 2.3 Draw up a lesson plan on the topic "Quadratic inequalities" for a Grade 11 class. Use a three-phased lesson (before, during and after), as explained in Tutorial Letter 501 (your study guide). Describe in detail what you are going to do in each of the three phases. You should have at least three activities in your lesson plan. 2.4 Describe in detail how each of the activities will be assessed. [33]
