Be sure you are comfortable with the following:

- Expanding brackets, e.g. Write 2(x-3)(2x+5) in standard form
- Factoring quadratic expressions, e.g. Write 2x
^{2}+ 5x + 2 in factored form. This includes:- Differences of squares, e.g. 9x
^{2}– 36 - Perfect squares, e.g. 9x
^{2}+ 12x + 4 - Expressions that require the removal of a common factor, e.g. 2x
^{2}+ 6x – 8 - Expressions in which a > 0, e.g. 3x
^{2}+ x – 2

- Differences of squares, e.g. 9x
- Sketching and labelling main features of a quadratic from its equation:
- vertex
- axis of symmetry
- zeroes
- shape
- function

- Finding the equation of a quadratic from its sketch
- Finding the equation of a quadratic given its zeroes and its y-intercept only
- Answering concept questions in the context of a real-world example
