40 progressive Edexcel GCSE Higher (1MA1) quadratic formula questions with full mark-scheme style worked solutions. Every line is explained and every mark is annotated at the exact point it would be awarded.
What’s inside:
Easy: identifying a, b and c, evaluating the discriminant, and solving quadratics that give whole-number answers.
Medium: solving to 2 decimal places, solving in surd form, rearranging into standard form first, and using the discriminant to find or rule out real roots.
Hard: forming quadratics from area and worded contexts (rejecting the negative root), simplifying surd solutions fully, and discriminant conditions for equal or real roots.
Every solution breaks the work down one step at a time, with the reasoning spelled out in plain English and the hardest questions given extra explanation. Typeset in LaTeX for clean mathematical notation.
Ideal for: Year 10 and 11 students sitting Edexcel GCSE Higher Mathematics (1MA1), plus tutors and teachers building targeted practice. Print-friendly, hand straight to students.
