Five graded worksheets on completing the square for GCSE Higher, with full mark schemes. From the basic form through to solving, turning points and reasoning.
How the series builds:
- Expressing in the form (x + a)² + b
- The form a(x + p)² + q (non-monic, negative leading coefficient, fractional a)
- Solving quadratics by completing the square (exact/surd roots)
- Turning points, lines of symmetry, least/greatest values, and meeting the x-axis
- Reasoning & proof (identities, always-positive arguments, discriminant reasoning)
Board-agnostic (AQA, Edexcel, OCR). Every question worked in the mark scheme. Print-and-go for lessons, homework, starters and revision.
