(a) Factorise \(g^2 + 4g\) (2)
(b) Factorise \(e^2 - 2e - 24\) (2)
| Scheme | Marks |
|---|---|
| \(g(g + 4)\) | B2 |
| (2) |
Notes
B2: Award B2 also for \((g \pm 0)(g + 4)\) oe
B1 for factors which, when expanded and simplified, give two terms, one of which is correct
except B0 for \((g + 2)(g - 2)\)
| Scheme | Marks |
|---|---|
| M1 | |
| \((e - 6)(e + 4)\) | A1 |
| (2) |
Notes
M1: for \((e \pm 6)(e \pm 4)\)
