| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| \(4cd - 20c\) final answer | 2 | M1 for \(4cd\) or \(-20c\) in final answer | Condone \(4dc\) \(4cd + -20c\) scores M1 only Do not accept eg \(4 \times c \times d\) |
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| \(3x^2 - 10x - 8\) final answer | 2 | M1 for at least three of the following terms correct \(3x^2 - 12x + 2x - 8\) | May be seen in a table \(-10x\) implies both \(-12x\) and \(2x\) |
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| \(x \leqslant 8\) | 2 | Mark final answer M1 for \(3x \leqslant 22 + 2\) or \(3x \lt 22 + 2\) or \(3x = 22 + 2\) or \(x \gt 8\) or \(x = 8\) If 0 scored, SC1 for answer \(x \leqslant \dfrac{20}{3}\) or \(x \leqslant 6\frac{2}{3}\) | Condone \(x \lt 8\) for 2 marks Condone 8 on answer line for M1 |
