A lesson introducing the quadratic formula for a middle to top set Year 9 class.
The proof is not derived.
Students will use the formula without their calculators and their answers will be surd expressions (some requiring simplication).
It is expected that students can facotorise quadratic expressions and are confident simplifying simple surds.
I act on feedback.
