17 Multiply out and simplify.
\((3x + y)(x + 2y)\) [3]
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| \(3x^2 + 7xy + 2y^2\) final answer | 3 | M2 for three correct terms from \(3x^2 + 6xy + [1]xy + 2y^2\) or M1 for two correct terms in the expansion above | More than 4 terms mark the worst 4 Accept values in a grid \(7xy\) is 2 terms Do not accept for M2 or M1 \(3x2y\), \(3xx\), \(2yy\), \(1x1y\) unless processed further |
