Can you factorise these quadratics before the timer runs out? ⏱️ I’ll show you the method, then it’s your turn: 5 quick ones where the x² has no number in front, 5 harder ones like 2x² + 7x + 6, a sneaky one that catches loads of students out, and finally a real WJEC GCSE exam question. No calculator needed!
Every question changes just one thing from the one before (a new number, a new sign), so you can see exactly how each change affects the brackets. Pause the video if you need more time!
