8
(a) Simplify \(6g - 5h - 4g + 2h\) (2)
(b) Factorise \(y^2 - 2y\) (1)
(c) Simplify fully \(\dfrac{p^3 \times p^4}{p^2}\) (2)
| Answer | Mark | Notes |
|---|---|---|
| \(2g - 3h\) | 2 | M1 for \(2g\) or \(-3h\) A1 for \(2g - 3h\) or \(-3h + 2g\) |
| Answer | Mark | Notes |
|---|---|---|
| \(y(y - 2)\) | 1 | B1 |
| Answer | Mark | Notes |
|---|---|---|
| \(p^5\) | 2 | M1 for \(\dfrac{p^{3+4}}{p^2}\) \(\left(= \dfrac{p^7}{p^2}\right)\) or \(p^{3-2} \times p^4\) \((= p^1 \times p^4)\) or \(p^3 \times p^{4-2}\) \((= p^3 \times p^2)\) A1 cao |
