Foundation November 2017 Paper 2 Q6
6
(a) Simplify fully.
(i) \(4(c + 2d) + 3(3c - 5d)\) [3]
(ii) \(4a \times 5b\) [1]
(b) Factorise fully.
(i) \(6g + 8h\) [1]
(ii) \(5x^2 - 15x\) [2]
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| (i) \(13c - 7d\) final answer | 3 | B2 for one term correct in final answer or M1 for [\(4(c + 2d)\)] = \(4c + 8d\) seen or [\(3(3c - 5d)\)] = \(9c - 15d\) seen | \(13c + -7d\) scores B2 only |
| (ii) \(20ab\) final answer | 1 | Accept \(20ba\) | |
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| (i) \(2(3g + 4h)\) final answer | 1 | Condone omission of final bracket | |
| (ii) \(5x(x - 3)\) final answer | 2 | M1 for \(5(x^2 - 3x)\) or \(x(5x - 15)\) or \(5x(x + 3)\) | Condone omission of final bracket |
