Foundation November 2023 Paper 1 Q28
28 Factorise \(\quad x^2 + 2x - 24\) [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| \((x + 6)(x - 4)\) | B2 | either order B1 \((x + a)(x + b)\) where \(ab = -24\) or \(a + b = 2\) |
Additional guidance
Condone a multiplication sign between the brackets
Condone missing final bracket
Ignore an attempt to solve \((x + 6)(x - 4) = 0\)
