(a) Simplify \(\;8d \times 7d\) (1)
(b) Expand \(\;4(3e - 5)\) (1)
(c) Factorise \(\;f^2 - 2f\) (2)
(d) \(H = g^3 + 6g\)
Work out the value of \(H\) when \(g = 2\) (2)
Work out the value of \(H\) when \(g = 2\) (2)

| \(56d^2\) | B1 |
| (1) |

|---|---|
| \(12e - 20\) | B1 |
| (1) |
Notes
B1: Accept \(-20 + 12e\)
| Scheme | Marks |
|---|---|
| \(f(f - 2)\) | B2 |
| (2) |
Notes
B2: Accept \((f \pm 0)(f - 2)\) oe
If not B2 then B1 for factors when expanded and simplified give 2 terms, 1 of which is correct except B0 for \((f + a)(f - a)\)
