Quadratics!

See at  https://www.desmos.com/calculator/tzgpvgn8p2 
Our next unit will be a brief exploration of quadratics with an emphasis on three things (click each for a short video on the topic):
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.
