| Answer | Mark | Notes |
|---|---|---|
| \(5(1 - 2m)\) | B1 | cao |
| Answer | Mark | Notes |
|---|---|---|
| \(2ab(a + 3b)\) | M1 | for \(2a(ab + 3b^2)\) or \(2b(a^2 + 3ab)\) or \(ab(2a + 6b)\) or \(2ab(\)2 term expression with terms in \(a\) or \(b\) or \(ab\), can include constants), eg \(2ab(1a + 3ab)\), \(2ab(1 + 3b)\) |
| A1 | for \(2ab(a + 3b)\) |
