By the end of this unit, students will be able to:
- understand the quadratic formula and its application in solving quadratic equations;
- apply the quadratic formula to find real and complex solutions for quadratic equations;
- interpret and analyze solutions in the context of real-world problems.
Curriculum Alignment: Key Stage 4: Algebra
- Solve quadratic equations {including those that require rearrangement} algebraically by factorising, {by completing the square and by using the quadratic formula}; find approximate solutions using a graph
