Flowchart showing the three brackets (x+3), (x+4), and (x+2) becoming a quadratic and then a cubic during expansion

A triple bracket such as (x+2)(x+5)(x−1)(x+2)(x+5)(x-1)(x+2)(x+5)(x−1) means three linear factors are being multiplied together. The safest method is to expand any two brackets first, simplify to a quadratic, then multiply by the remaining bracket.

Step-by-step lessons covering Oxford AQA IGCSE Maths Expanding Triple Brackets for Core and Extended tier. Each lesson works through exam-style questions in Paper 1 and Paper 2 (Core: 1C and 2C; Extension: 1E and 2E) format. Since content from any part of the specification can appear on either paper, keep number and algebra fluency sharp throughout the course rather than leaving it until near the exam.
