Quadratic Equations & the Formula | OCR GCSE Maths Higher | 40 Worked Examples (J560)

Quadratic equations for OCR GCSE (9-1) Mathematics Higher tier (J560). 40 exam-style questions with fully worked, mark-scheme-annotated solutions: solving by factorising (including ax^2+bx+c with a not 1), difference of two squares, solving by the quadratic formula to 2 decimal places, completing the square in exact form, rearranging to standard form, forming quadratics from context (rectangle area, consecutive integers, Pythagoras), and algebraic-fraction equations that reduce to a quadratic. Progressive Easy to Challenging difficulty. Every working line is annotated, with OCR M/A/B marks folded in on the real mark-scheme lines. Built for OCR’s no-formula-sheet exam: the quadratic formula is Higher content you must recall from memory, so the pack opens with the key formulae and the method-choice strategy. Calibrated against OCR J560 past papers and mark schemes, not ported from another board (OCR does not examine the discriminant). Ideal for revision, homework, and 1-1 tuition.
