Exercise 4.4 Class 9 Maths | Exploring Algebraic Identities | NCERT Ganita Manjari | 2026-27 Exploring Algebraic Identities | Exercise 4.4 | Class 9 Maths (Ganita Manjari) | Brain Tree – Maths with Akshay Sir Crack factorisation by splitting the middle term! In this video we solve the complete Exercise Set 4.4 from Chapter 4 — completing factor identities, finding products fast using a smart identity, and factorising tricky expressions using every method from the chapter. 🚀 🔑 Identities & methods used in this exercise: • (x + a)(x + b) = x² + (a + b)x + ab (splitting the middle term) • a² = (a + b)(a − b) + b² (Śhrīdharāchārya's method) • (a + b)² = a² + 2ab + b² • (a − b)² = a² − 2ab + b² • (a + b + c)² = a² + b² + c² + 2ab + 2bc + 2ca ✅ What you'll learn: • Splitting the middle term to factorise quadratics • Filling in the blanks to complete factor identities • Finding products & squares fast without multiplying directly • Factorising perfect-square and three-variable expressions 📘 Solved in this video: • Worked Examples (10, 11, 12): x² + 7x + 12, x² + 11x + 30, x² − 5x + 6 • Q1: Fill in the blanks — s² − 11s + 24, 3x² − 4x − 7, 10x² − 11x − 6, 6x² + 7x + 2 • Q2: Find products without multiplying — 41², 27², 23×17, 135², 97², 18×29, 34×43, 205² • Q3: Factorise — 9a² + b² + 4c² − 6ab + 12ac − 4bc, 16s² + 25t² − 40st, r² − r − 42, 49g² + 14gh + h², 64u² + 121v² + 4w² − 176uv − 32uw + 44vw 🎯 Perfect for: Class 9 students, NCERT / Ganita Manjari learners, and anyone revising algebraic identities for school and board exams. 👍 LIKE if this helped, 🔔 SUBSCRIBE to Brain Tree – Maths with Akshay Sir for the full Chapter 4 series, and 💬 drop your doubts in the comments — I reply! #Class9Maths #Class9 #Class9Mathematics #GanitaManjari #NCERTClass9 #CBSEClass9 #Class9NCERT #9thClassMaths #Class9Algebra #Class9Chapter4
