(b) Expand and simplify \(\quad (x - 3)(x + 1)\) (2)
| Scheme | Marks |
|---|---|
| \(e^6\) | B1 |
| (1) |
Notes
B1: cao
| Scheme | Marks |
|---|---|
| \(x^2 - 3x + x - 3\) | M1 |
| Correct answer scores full marks (unless from obvious incorrect working) Answer: \(x^2 - 2x - 3\) | A1 |
| (2) | |
| (3 marks) |
Notes
M1: for any 3 correct terms or for 4 out of 4 correct terms ignoring signs or for \(x^2 - 2x \ldots\) or for \(\ldots -2x - 3\)
