All my resources have been created to use with classes I teach. Often I've created resources because, for a particular topic, I haven't been happy with the number/standard of the examples in a textbook. Sometimes I've created worksheets for certain topics (e.g. graph transformations) because I feel my classes will make greater progress on a printed worksheet than trying to work from a textbook. I always aim to produce high-quality resources that improve the students' learning and understanding.

This worksheet focuses on quadratic expressions where the question requires the candidate to show that the expression is always positive, never negative, etc.

There is an introductory activity where students practise thinking about expressions of the form ax^2 + b, or a(x-b)^2 + c - doing a quick sketch of the graph and then deciding whether they are always positive, never negative, always negative or never positive.

Next is a page of example proofs to work through with your class, followed by an exercise with 15 questions for your class to attempt themselves.

Fully worked solutions to the examples and the exercise are included.
