*Learning Goal: Develop procedural fluency with solving quadratics using multiple methods.*

# Classwork:

- Estimation 180 – Day 80 (Andrew Stadel)
- Warm Up
- Handout (Inspired by Geoff Krall)

# Standards:

**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
