What examiners said

Many candidates had a good understanding of how to expand the three brackets, and the majority gave a correct expansion. After expanding two brackets, some chose to simplify to three terms before dealing with the final bracket. This sometimes led to errors such as –5x + 4x = –9x. However, those that did not simplify had more terms to deal with in the final expansion and were more likely to slip up...

— Examiner report, May/June 2025, 0580/43 Q10(b) (Cambridge)

Almost all candidates found the correct value with just a few making a slip with the numeracy.

— Examiner report, February/March 2023, 0580/42 Q5(b)(i) (Cambridge)

In this part, candidates had to simplify the expression by multiplying the numbers and finding the power for w. Often the w was missed out as candidates gave an answer of 4815 . This was the most successful part of this question.
