@sciencespheretutoring: Completing the square trips up almost everyone the first time they meet it. Here's the clean way to never lose those marks again. 📐 The rule for x² + bx + c: 1️⃣ Halve b, put it in the bracket 2️⃣ Square it 3️⃣ Subtract it back That's it. Same three moves, every single question. Example: x² + 6x + 1 Halve 6 → 3. Bracket: (x + 3)² Square 3 → 9. Subtract it: (x + 3)² − 9 + 1 Simplify: (x + 3)² − 8 Halve, square, subtract. Once it clicks, it's a pattern for life — and it hands you the turning point of the graph for free.
