Foundation November 2021 Paper 1 Q32
32 Factorise \(\quad x^2 + 7x + 10\) [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| \((x + a)(x + b)\) | M1 | where \(a + b = 7\) or \(ab = 10\) |
| \((x + 2)(x + 5)\) | A1 |
Additional guidance
Ignore attempts to solve their \((x + a)(x + b) = 0\) for M1A0 or M1A1
Condone missing final bracket
Ignore a check of a correct solution (multiplying out or similar)
