Exam Tips for Success
📘 Follow these expert tips while practicing this exercise:
- Always start by identifying the common factor.
- If none exists, check for special identities such as (a² - b²), (a ± b)², or (a³ ± b³).
- Group terms carefully when expressions get lengthy.
- After factorizing, multiply back to verify your answer.
- Revise Exercises 4.4 to 4.7 before attempting this one — it’ll make 4.8 easier.
💡 Pro Tip: Exercise 4.8 acts as a chapter test. Completing it without help means you’ve mastered Chapter 4 completely.
