| Answer | Mark | Mark scheme |
|---|---|---|
| \(6x^2 - 11x - 10\) | M1 | for expanding bracket to obtain 4 terms with all 4 correct without considering signs or for 3 terms out of 4 correct with correct signs |
| A1 | cao |
Additional guidance
NB \(6x^2 - 11x\) or \(-11x - 10\) can be considered 3 terms out of 4 correct with correct signs
