1. Completing the Square

2. Complex Numbers

3. Applying quadratics to solve geometric problems

*Prior Knowledge Alert:*

We should be building on the work you have already done in Algebra 1 on quadratics and we will largely assume the following three things (click each for a short video on the topic):

1. Factoring

2. Quadratic Formula

3. Graphing Quadratic Functions

Please find a couple videos that introduce the big concepts from this short unit on quadratics below as well as the presentations, reference sheets, problem sets, and homeworks for the coming weeks.

**Here is our collective brainstorm on Linear and Quadratic Functions as well as some factor by grouping and sum and difference of cube examples from class.**

**Linear-Quadratic Brainstorm Summary**

**Grouping and Sum and Difference of Cubes Class Examples**

**Completing the Square Class Examples**

**Solving Quadratic Equations Class Examples (practice problems with answers)**

**Homework Due October 19th**
