(a) Simplify \(2e^2f \times 5e^3f\) (2)
(b) Factorise \(x^2 - 5x - 6\) (2)
| Scheme | Marks |
|---|---|
| \(10e^5f^2\) | B2 |
| (2) |
Notes
B2: If not B2 then award B1 for
\(ke^5f^2, k \ne 10\) or \(10e^5f^a\) or \(10e^bf^2\) \(a, b \ne 0\)
| Scheme | Marks |
|---|---|
| \((x - 6)(x + 1)\) | B2 |
| (2) | |
| (4 marks) |
Notes
B2: If not B2 then award B1 for
\((x - 1)(x + 6)\) or
\((x - 3)(x - 2)\) or \((x + 3)(x - 2)\) or \((x - 3)(x + 2)\)
