Edexcel IGCSE Math A Higher 2.7.HA harder quadratic factorisation
Practise the single harder-quadratic question by forming factors for 8x²-6x-275 and choosing the value of x that fits the diagram.
How this is tested
- Factorise or solve a quadratic with leading coefficient greater than 1.
- Choose the valid root for the context and reject the value that cannot fit the diagram.
