What examiners said
There were some very good responses with clear working that led to the answer. Many candidates made sign errors when collecting terms. Some collected the terms correctly, but then made a sign error when performing the final division, leading to the common wrong answer 2.
— Examiner report, October/November 2023, 0607/13 Q17 (Cambridge)
This part involved clearing algebraic fractions to create ( 3 x + 2 ) = 8 × 2 . Many candidates reached this stage and decided to expand the brackets to obtain a standard quadratic equation and then solve it by factorising or using the formula. A few of the stronger candidates spotted the efficient method of 3x + 2 = ±4 .
— Examiner report, May/June 2023, 0607/43 Q6(c) (Cambridge)
This part was answered quite well as long as the equation was rearranged into the form ax 2 + bx + c = 0 followed by use of the formula.
