Edexcel IGCSE Math A syllabusMath A 4MA1First assessment 2018

Practise factorised-quadratic questions by reusing the factorisation of x²+bx+c and then setting each bracket equal to zero.

How this is tested

  • Use integer factors of c that add to b, then set each bracket equal to zero.
  • Follow through from an earlier factorisation and state both roots in simplified form.
