1. Brackets An introduction to using brackets in algebra

2. Simplifying 7x + 7y + 7p + 7w 7(x + y + p + w) 7x + 7y + 7p + 7w

3. Simplifying 9m + 9n + 9p + 18c 9(m + n + p + 2c) 9m + 9n + 9p + 18c

4. Factorise 3w + 3p + 6q + 18a 3(w + p + 2q + 6a)

5. Expand 3(w + p + 2q + 6a) 3w + 3p + 6q + 18a

6. Factorise 8k + 8m + 16 8(k + m + 2)

7. Expand 5(g – 2p + 7) 5g - 10p + 35

8. Expand -2(w – 3d + 5) -2w + 6d - 10

9. Factorise 20a + 15b + 25c 5(4a + 3b + 5c)

10. Exercise Factorise: 5a + 5b 9m – 9n 3 + 6t 4a + 4b – 4c 4w – 6 10d – 2e -2f – 4j Expand: 3(m – n) 2(b – 50) -3(r – t) Solve 4(2x – 3) = 20

11. Exercise Factorise: 5a + 5b = 5(a + b) 9m – 9n = 9(m – n) 3 + 6t = 3(1 + 2t) 4a + 4b – 4c = 4(a+b-c) 4w – 6 = 2(2w – 3) 10d – 2e = 2(5d – e) -2f – 4j = -2(f + 2j) Expand: 3(m – n) = 3m – 3n 2(b – 50) = 2b – 100 -3(r – t) = -3r + 3t Solve 4(2x – 3) = 20 8x – 12 = 20 8x = 32 x = 4
