Developing problem-solving resources, especially for gifted students, can be quite difficult. The following worksheet is designed for Year 10, 11 or 12 Mathematics students who would like to improve their problem solving ability using quadratics. This would be equivalent to Algebra I or II students in the American system. In addition to questions, I have provided some 'handy hints' for (students) and teachers who may need to be pointed in the right direction, without telling you the answer.
