Expanding and Factorising | OCR GCSE Maths Higher | 40 Worked Examples (J560)

Expanding and factorising for OCR GCSE (9-1) Mathematics Higher tier (J560). 40 exam-style questions with fully worked, mark-scheme-annotated solutions: expanding single brackets, expanding and simplifying two brackets, perfect squares, expanding a product of three brackets (Higher), factorising by common factors, factorising quadratics x^2+bx+c, the difference of two squares, factorising ax^2+bx+c by splitting the middle term (Higher), factorising fully, simplifying algebraic fractions by factorising, and show-that/prove questions. Progressive Easy to Challenging difficulty. Every working line is annotated, with OCR M/A/B marks folded in on the real mark-scheme lines and the OCR partial-credit cascade shown. Built for OCR’s no-formula-sheet exam: the expansion identities you must recall are set out up front, and the pack notes that this skill is examined on the non-calculator paper J560/05 (the middle paper). Calibrated against OCR J560 past papers and mark schemes, not ported from another board. Ideal for revision, homework, and 1-1 tuition.
