In this activity, you will discuss the questions with the assigned partner(s) for Practice 4.

On your own, you must to submit your answers via the GoogleForm.

Estimated duration: 30minutes

---

This practice requires you solve the inequalities and think how it could be presented in a number line (making connection in the visual form)

• You did this in Unit 2 (without solving inequalities)

Questions 10 to 20 is where the discussion becomes useful. 

- to look "deeper" "within" the inequality (Relationships!)

Algebra: Application (I)

Detailed working of the 2 questions that we disucssed in the previous lesson.

In the working below, 2 methods are shown: 

• Method 1: Factorisation
• Method 2: Expansion

You will find method 1 easier to manage though many of you are incline to expand the expression (Method 2). Do note Method 2 usually requires us to apply what's to be covered in Sec 2.
