Completing the Square | OCR GCSE Maths Higher | 40 Worked Examples (J560)

Completing the square for OCR GCSE (9-1) Mathematics Higher tier (J560). 40 exam-style questions with fully worked, mark-scheme-annotated solutions: writing x^2+bx+c in the form (x+a)^2+b, the non-monic a(x+p)^2+q case, solving quadratics by completing the square with surd-form answers, finding turning points and minimum/maximum values, and ‘show that / no real solutions’ reasoning. 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: completing the square is Higher-only (spec 6.01f) and exact surd work is set on the non-calculator paper J560/05. Calibrated against OCR J560 past papers and mark schemes, not ported from another board. Ideal for revision, homework, and 1-1 tuition.
