27
(a) Expand \(3(x + 4)\) (1)
(b) Expand \(x(x^2 + 2)\) (2)
(c) Factorise \(x^2 - 6x\) (1)
| Answer | Mark | Notes |
|---|---|---|
| \(3x + 12\) | 1 | B1 for \(3x + 12\) or \(12 + 3x\) |
| Answer | Mark | Notes |
|---|---|---|
| \(x^3 + 2x\) | 2 | M1 for the intention to multiply both terms in the bracket by \(x\) A1 for \(x^3 + 2x\) OR B2 for \(x^3 + 2x\) [B1 for \(x^3\) or \(2x\) seen] |
| Answer | Mark | Notes |
|---|---|---|
| \(x(x - 6)\) | 1 | B1 for \(x(x - 6)\) or \((x - 6)x\) |
