(a) Simplify \(\;2e - 3f + 4e - 7f\) (2)
(b) Expand and simplify \(\;5(4x + 3) - (3x - 1)\) (2)
(c) Factorise fully \(\;4p + 6pq\) (2)
| Scheme | Marks |
|---|---|
| M1 | |
| \(6e - 10f\) oe | A1 |
| (2) |
Notes
M1: for \(6e\) or \(-10f\)
A1: do not award if in incorrect attempt at simplification is seen eg \(-4ef\)
| Scheme | Marks |
|---|---|
| \(20x + 15 - 3x + 1\) | M1 |
| \(17x + 16\) | A1 |
| (2) |
Notes
M1: for 3 correct terms
A1: SC : B1 for \(5x + 20\)
| Scheme | Marks |
|---|---|
| \(2p(2 + 3q)\) | B2 |
| (2) | |
| (6 marks) |
Notes
B2: If not B2 then award B1 for
\(2(2p + 3pq)\) or \(p(4 + 6q)\)
or \(2p\)(a two term expression)
or \(x(2 + 3q)\) where \(x \ne 2p\)
