Factorisation of Quadratic Expressions in the form ax^2 + bx + c where a is 1

Mastering quadratic factorisation doesn't have to be a headache! In this video, we break down how to factorise expressions like x^2 + 5x + 6 using two powerful methods. We start with the Multiplication Frame to help you visually understand how terms multiply to form a quadratic. Then, we level up to the "Magic Pair" method, where you’ll learn to quickly identify factors using the Product (c) and Sum (b) shortcut. 📌 What You’ll Learn: The Grid Setup: How to organize x^2 and constant terms. The Magic Pair: Finding the perfect numbers that satisfy two rules at once. The Shortcut: Moving from drawing frames to mental math for faster problem-solving. 🧮 Quick Reference: For any quadratic expression x^2 + bx + c: Product: Find two numbers that multiply to get c. Sum: Ensure those same two numbers add up to get b. Result: Place them straight into the brackets: (x + ?)(x + ?) Example used in video: x^2 + 5x + 6 Factors of 6 that add to 5 are 2 and 3. Final Answer: (x + 2)(x + 3)
