Quadratic Equations and factorising
These questions from my own experience were some of the hardest in the GCSE maths course and need careful explaining in order to understand them properly and be able to complete them independently.These questions involve a quadratic equation such as the generic ax2 + bx + c = 0 where a, b and c are constantsThe objective is to usually factorize this equation into two brackets (x - d)(x - e) = 0 for example
