Foundation June 2018 Paper 3 Q20
20 Expand and simplify \(5(p + 3) - 2(1 - 2p)\) (2)
| Answer | Mark | Mark scheme |
|---|---|---|
| \(9p + 13\) | M1 | for method to expand one bracket, eg \(5 \times p + 5 \times 3\ (= 5p + 15)\) or \(2 \times 1 - 2 \times 2p\ (= 2 - 4p)\) or \(-2 \times 1 - 2 \times -2p\ (= -2 + 4p)\) |
| A1 | cao |
Additional guidance
If an attempt is made to multiply by \(-2\) in the second brackets then it must be done consistently.
