Work through the chapter
Build each skill before putting the ideas together.
- 01
Expanding and factorising quadratics
Expand two brackets, then work backwards to factorise a monic quadratic.
- 02
Solving quadratic equations
Use square roots or factorisation to find every solution, then check the roots.
- 03
Graphing parabolas
Connect a quadratic rule, its table and its graph, then read roots, symmetry and a turning point.
- 04
Quadratic models and applications
Turn a short practical problem into a quadratic rule, solve it and choose answers that fit the situation.
