ACS (Independent) Mathematics Department / Mathematics HL / Year 5 / 2018 Final Examination Paper 1 1 Full marks are not necessarily awarded for a correct answer with no working. Answers must be supported by working and/or explanations. In particular, solutions found from a graphic display calculator should be supported by suitable working, e.g. if graphs are used to find a solution, you should sketch these as part of your answer. Where an answer is incorrect, some marks may be given for a correct method, provided this is shown by written working. You are therefore advised to show all working. Section A Answer all questions in the boxes provided. Working may be continued below the lines if necessary. 1. [Maximum mark: 5] Find the term independent of x in the expansion of ( 1 √𝑥 − 1) 4 (1 − 𝑥)2.
