In this video, we will solve *Exercise 2.4 Questions 6, 7, and 8* from the *NCERT textbook**, based on the **polynomial identity:* $$ x^3 + y^3 + z^3 - 3xyz = (x + y + z)(x^2 + y^2 + z^2 - xy - yz - zx) $$ This identity is not just important for your board exams, but also forms the foundation for many algebraic expressions you'll encounter in higher classes. We're breaking it down with *easy steps, clear logic, and shortcut methods* so every student can understand and apply this identity easily! --- ✨ *What You’ll Learn in This Video:* ✅ How to verify the identity using values ✅ Step-by-step explanation of Q6, Q7, and Q8 ✅ Concept behind the identity $x^3 + y^3 + z^3 - 3xyz$ ✅ Real exam-focused explanation to build your concept ✅ Useful tips and tricks to remember identities for exams --- 📌 *Topics Covered in This Video:* 📍 Q6: Verifying identity for given values 📍 Q7: Factorisation of $x^3 + y^3 + z^3 - 3xyz$ 📍 Q8: Proof that $x^3 + y^3 + z^3 = 3xyz$ when $x + y + z = 0$ --- 🔔 *Why Watch This Video?* ✨ Clear Concept Building ✨ Fully NCERT Based ✨ Great for CBSE Class 9 Exam Preparation ✨ Simple Language + Visual Explanation ✨ Learn the logic, not just the steps! --- 📚 *NCERT Class 9 Maths – Chapter 2: Polynomials* This chapter covers important algebraic concepts including types of polynomials, degree, coefficients, zeroes of polynomials, and standard identities. Exercise 2.4 focuses on algebraic identities — a key part of scoring well in exams. --- 🧮 *About This Identity:* The expression $x^3 + y^3 + z^3 - 3xyz$ is a special identity used when all three variables are involved. When $x + y + z = 0$, the identity simplifies to: $$ x^3 + y^3 + z^3 = 3xyz $$ This is commonly asked in CBSE board exams, school tests, and Olympiads. --- 📝 *Homework for You:* Try verifying the identity for these values: 1. $x = 2, y = 3, z = 4$ 2. $x = -1, y = 0, z = 1$ Let us know your answers in the comments below! We’ll respond with solutions! ✨ --- 📌 *Important for:* ➡️ CBSE Class 9 Students ➡️ School Unit Tests & Final Exams ➡️ Olympiad and NTSE Aspirants ➡️ Anyone looking to strengthen Algebra concepts --- 📲 *Stay Connected:* 📢 Like | 👍 Share | 💬 Comment | 🔔 Subscribe 📌 Don’t forget to hit the bell icon so you never miss an update from our Class 9 series! 📽️ *Watch More:* 🎥 Class 9 Maths – Polynomial Introduction 🎥 Exercise 2.2 & 2.3 Full Solutions 🎥 Polynomial Identities Made Easy --- 📈 *Boost Your Grades with Us!* We simplify tough topics so you can study smarter, not harder.
