| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| \(2a + 3b\) final answer | 2 | B1 for \(2a\) or \(3b\) in answer If 0 scored, SC1 for correct answer seen then spoilt | Eg \(2a + 3b = 5ab\) |
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| (i) \(4x + 12\) final answer | 1 | ||
| (ii) \(x^2 + 3x - 10\) | 2 | Mark final answer B1 for 3 of \(x^2\), \(5x\), \(-2x\), \(-10\) | [+]\(3x\) counts as two terms For B1 could be in a grid |
