Learning Goal: Develop procedural fluency with multiple methods of solving quadratic equations.
- Students work on computers as if it were a Personalized Growth Day
- Desmos Challenge
- Handout to see lines better
- Common Core
HSA.REI.B.4.B – Solve quadratic equations by inspection (e.g., for x² = 49), taking square roots, completing the square, the quadratic formula and factoring, as appropriate to the initial form of the equation. Recognize when the quadratic formula gives complex solutions and write them as a ± bi for real numbers a and b.
- TEKS (2015-16)
- A.8(A) – solve quadratic equations having real solutions by factoring, taking square roots, completing the square, and applying the quadratic formula
