| Expand this expression: 5(2x+3) | 1. 5 (times) 2x = 10x 2. 5 (times) 3 = 15 3. = 10x +15 |
| Expand and Simplify 9(x-2) | 1. 9 (times) x = 9x 2. 9 (times) -2 = -18 3. = 9x - 18 |
| Expand -3y(4 -3y) | 1. -3y (times) 4 = -12y 2. -3y (times) -3y = +9y 3. = -12y + 9y |
| Expand 4x(x+3) -2x(3x-7) | 1. 4x (times) x =4x^2 2. 4x (times) 3 = 12x 3. -2x (times) 3x = -6x 4. -2x (times) -7 = +14x 4. = 4x^2 +20x |
| Factorise 3x + 9 | 1. Divide by common value = 3 2. Place remainder of values into brackets 3. 3(x+3) |
| Factorise 3x^2 - 9xy | 1. Divide by 3x 2. 3x(x-3y) remaining values 3. Cannot be Simplified any further |
| Factorise 10y^2 - 5y | 1. Divide by 5y 2. 5y(2y - 1) remaining values 3. Cannot be simplified further |
