Foundation November 2020 Paper 1 Q25
25 Factorise fully \(\quad 2x^2 + 6x\) [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(2x(x + 3)\) | B2 | B1 \(x(2x + 6)\) or \(2(x^2 + 3x)\) |
Additional guidance
| Condone missing final bracket \(\;2x(x + 3\) Condone \((2x + 0)(x + 3)\) | B2 B2 |
| Condone multiplication signs for B1 but not B2 Condone \(1x\) for \(x\) for B1 but not B2 Condone incorrect algebraic notation for B1 but not B2 eg \(x(x2 + 6)\) | |
| Do not allow further work for B2 but ignore further work for B1 eg \(2x(x + 3) = 2x(3x)\) eg \(x(2x + 6) = x(8x)\) | B1 B1 |
