Pure 4: Binomial Expansion

A free binomial expansion worksheet for A-Level and International A-Level Maths, covering the binomial expansion content of Pure Mathematics 4. It works through the expansion and Pascal's triangle, negative and fractional coefficients, finding a specific term, comparing coefficients, products: expand, then use it and approximations. Questions are grouped into fluency, reasoning and problem solving, so you build the technique first and then apply it to the kind of unfamiliar, multi-step questions that separate grades in the exam. Written to match the style and presentation of Edexcel International A-Level and 9MA0. Full step-by-step solutions are provided in a separate PDF, so you can check your method as well as your answer.
