23
(a) Expand \(2m(m + 3)\) (1)
(b) Factorise fully \(3xy^2 - 6xy\) (2)
| Answer | Mark | Notes |
|---|---|---|
| \(2m^2 + 6m\) | 1 | B1 cao |
| Answer | Mark | Notes |
|---|---|---|
| \(3xy(y - 2)\) | 2 | B2 for \(3xy(y - 2)\) (B1 for \(3x(y^2 - 2y)\) or \(3y(xy - 2x)\) or \(xy(3y - 6)\) or \(3xy\)(a two term algebraic expression)) |
