Higher November 2024 Paper 3 Q11
11 Factorise fully \(\quad 12t + 4t^3\) [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(4t(3 + t^2)\) | B2 | B1 \(4(3t + t^3)\) or \(2t(6 + 2t^2)\) or \(2(6t + 2t^3)\) or \(t(12 + 4t^2)\) |
Additional guidance
| Ignore any “solutions” seen | |
| Ignore any attempts to complete the square with the final answer | |
| Condone \(4t \times (3 + t^2)\) | B2 |
| Condone \(4t(3 + 1t^2)\) | B2 |
| Condone \(4 \times (3t + t^3)\) | B1 |
| \((4t + 0)(3 + t^2)\) | B1 |
| Do not ignore further incorrect algebraic simplification for B2 |
