1. Expand Brackets Low C C B
Thursday, 30 May 2019
This means ‘get rid’ of the brackets in cases like:
3(x + 2)
4(2x + 3)
x(x + 3)
3(x – 2) + 2(x – 3)
(x + 3)(x – 2)
Low C C B

2. (x + 4)(x + 2)
This can be written as:

3. (x + 4)(x + 2)
This can be written as:
x(x +2) + 4 (x + 2)

4. (x + 4)(x + 2) x(x +2) + 4(x + 2) x X (x + 2) + 4 X (x + 2)
This can be written as:
x(x +2) + 4(x + 2)
x X (x + 2) + 4 X (x + 2)

5. (x + 4)(x + 2) x(x +2) + 4(x + 2) x X (x + 2) + 4 X (x + 2)
This can be written as:
x(x +2) + 4(x + 2)
x X (x + 2) + 4 X (x + 2)
x X x + x X X x + 4 X 2

6. (x + 4)(x + 2) x(x +2) + 4(x + 2) x X (x + 2) + 4 X (x + 2)
This can be written as:
x(x +2) + 4(x + 2)
x X (x + 2) + 4 X (x + 2)
x X x + x X X x + 4 X 2
x2 + 2x + 4x + 8 = x2 + 6x + 8
