14 Factorise \(\quad 12a + 15b\) [1 mark]
| Answer | Mark | Comments |
|---|---|---|
| \(3(4a + 5b)\) | B1 |
Additional guidance
| Condone missing final bracket ie \(3(4a + 5b\) | B1 |
| Allow multiplying back out to check their answer | |
| Further incorrect work after a correct response is B0 eg \(3(4a + 5b) = 27ab\) | B0 |
| \(3(a4 + b5)\) | B0 |
| \(3 \times (4a + 5b)\) | B0 |
