Expanding vs Factorising Explained (Step-by-Step)
Factorising in maths is more than numbers — it’s pattern recognition, logic, and structure.
• When teaching, linking “expanding” and “factorising” as opposites helps students build confidence in algebra.
• A simple classroom moment: showing how 12y² – 4y becomes 4y(3y – 1).
• Education isn’t about tricks — it’s about making connections clear. #Teaching #MathematicsEducation
• Factorisation demonstrates how clarity emerges from structure — something we aim for in every learning environment.
因式分解其实就是找共同因子 📚 (Factorising is really just finding the common factor)
• 代数展开与因式分解，其实是一对“反义词” 🔄 (Expanding and factorising are actually opposites)
• 学会把式子放进括号，你就掌握了因式分解 ✍️ (Learn to put expressions into brackets, and you’ve mastered factorising)
• 12y² – 4y = 4y(3y – 1)，一步到位 ✅ (12y² – 4y = 4y(3y – 1), done in one step)
• 数学小技巧：先找最大公因数，再放进括号！ (Math tip: Find the biggest common factor first, then put it in brackets!)
