Special Cases: The Difference of Two Squares & Missing Terms

👉Full courses https://www.mathsadviceonyourdevice.com/ ⚠️ What happens when a quadratic equation is “missing” a term? 0:00 – Review: the Area Method 0:08 – The “zero middle term” mystery 0:58 – Geometric proof: x² − 9 1:19 – Handling coefficients: 2x² − 200 1:40 – Quadratics with no constant term (single bracket) 2:20 – Practice and summary In this lesson, we apply the Reverse Area Method to special cases that often confuse students — including the Difference of Two Squares and quadratics with no middle or no constant term. By treating x² − 9 as a quadratic with a 0x middle term, students see that the same structural logic still applies. Using geometry, we visually show that the area of x² − 3² is identical to a rectangle with sides (x + 3) and (x − 3) No tricks. No memorisation. Just structure that makes sense 🧠📐 🎯 Key Takeaways for Teachers & Students 🔹 The 0x Concept Why missing middle terms must be opposites (additive inverses) so they cancel 🔹 Difference of Two Squares A geometric proof that a² − b² = (a − b)(a + b) 🔹 Leading Coefficients Made Clear Why expressions like 2x² − 200 should be simplified before factoring 🔹 Single-Bracket Factorisation Understanding x² + x as a rectangle with width x Who This Video Is For 🎯 Teachers who want students to understand factoring 📘 Students confused by “missing” terms 🚀 Anyone preparing for advanced algebra or Calculus Access full courses, quizzes, and worksheets here: 👉 https://www.mathsadviceonyourdevice.com/ 💎 Want More Like This? 🔎 Have a topic you’d like explained visually?
