Quadratic Equations
Akopọ
Quadratic equations arise whenever a problem involves a squared term: the path of a thrown ball, the area of a resized rectangle, or the profit curve of a business. Learning to solve them unlocks a wide range of real-world applications and appears in almost every Higher-tier exam paper.
You will start with factorisation at Foundation level, then move to the quadratic formula and completing the square at Higher. The topic also covers forming quadratic equations from context and solving systems where one equation is linear and the other quadratic.
Awọn Afojusun
- Solve quadratic equations by factorisation (limited to x^2 + bx + c = 0 at Foundation)
- [Higher] Solve quadratic equations by using the quadratic formula or completing the square
- [Higher] Form and solve quadratic equations from data given in a context
- [Higher] Solve simultaneous equations in two unknowns, one equation being linear and the other being quadratic
