Lesson 1: Learning Objective
Topic: Factorising and Solving Quadratic Equations with (Coefficient of x suared greaster than 1)
Retrieval Activities
Recall
- Recall how to identify the Highest Common Factor (HCF) and factorise simple algebraic expressions.
Review
- Find two numbers that multiply to 24 and add to 10. Explain how this strategy helps when factorising quadratic expressions.
Apply
-
Solve the equation:
(x+5)(x−2)=0
(x + 5)=0 or (1-2) =0
x = -5 or x = 2
Can you explain why each factor can be set equal to zero.
Reflect
- In one complete mathematical sentence, explain why factorising a quadratic equation makes it easier to determine its solutions.
