(a) \(6x^2 + 9x\) [2]
(b) \(x^2 + 8x + 15\) [2]
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| \(3x(2x + 3)\) final answer | 2 | B1 for \(x(6x + 9)\) or \(3(2x^2 + 3x)\) or correct answer seen and spoilt | Condone missing final bracket and e.g. \(2 \times x\) |
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| \((x + 5)(x + 3)\) final answer | 2 | B1 for \((x + a)\) and \((x + b)\) where \(ab = 15\) or \(a + b = 8\) | Condone missing final bracket |
