Expand Brackets Low C C B 21 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

Take care with the minus sign x(x + 4) – 3(x + 2) Take care with the minus sign x X (x + 4) – 3 X (x + 2)

x(x + 4) – 3(x + 2) x X (x + 4) – 3 X (x + 2) Take care with the minus sign x X (x + 4) – 3 X (x + 2) x X x + x X 4 – 3 X x – 3 X 2 Now, it’s –3 times x and –3 times 2

Now, it’s –3 times x and –3 times 2 x(x + 4) – 3(x + 2) This means x times (x + 4) This means -3 times (x + 2) x X (x + 4) – 3 X (x + 2) x X x + x X 4 – 3 X x – 3 X 2 x2 + 4x – 3x – 6 Now, it’s –3 times x and –3 times 2

Now, it’s –3 times x and –3 times 2 x(x + 4) – 3(x + 2) This means x times (x + 4) This means -3 times (x + 2) x X (x + 4) – 3 X (x + 2) x X x + x X 4 – 3 X x – 3 X 2 x2 + 4x – 3x – 6 x2 + x – 6 Now, it’s –3 times x and –3 times 2 Tidy up
