Quadratics Past Paper Questions (iGCSE Additional Maths Cambridge)
Studying for your Additional Maths iGCSE?
On this page you'll find plenty of questions on quadratic functions from Cambridge IGCSE past papers.
Students should be able to solve quadratics by factorising, completing the square, or using the quadratic formula. More complex equations can also be solved by making a substitution that transforms them into a quadratic.
They should also be able to sketch quadratic graphs, identifying the x- and y-intercepts. By completing the square, they can determine the minimum or maximum value of a quadratic function.
Further skills include using the discriminant to determine the number of roots, and solving quadratic inequalities either graphically or algebraically.
