Exam Tips for Success
📘 Follow these expert tips:
- Start by identifying the common factor.
- If none, check for special identities like (a² − b²), (a ± b)², (a³ ± b³).
- Group terms carefully in long expressions.
- After factorizing, multiply back to verify.
- Revise Exercises 4.4 to 4.7 before attempting 4.8.
💡 Pro Tip: Exercise 4.8 acts as a chapter test — solving it without help means you’ve mastered the chapter.
