What you'll learn

1. 1

   Imagine 12 biscuits on a tray. You can split them into equal groups — 3 groups of 4, or 2 groups of 6. Those numbers that multiply to make 12 are its factors! 🍪

2. 2

   Which pair of numbers multiply to make 12? 🍪

3. 3

   Show 3 rows of 4 biscuits to see the factors of 12. 🍪

   Let's factorise 6x + 9 together. That means we find the biggest number that divides both parts. 📝

5. 5

   Now factorise 4x + 8 by dragging the common factor outside the brackets. 🎯

6. 6

   What is the common factor of 6x and 15? ❓
