Quadratics Playlist for Algebra 2

Quadratic equations are basically code for all variations of y = x squared. They form parabolas, which are bowl shaped graphs, either facing up or down. (They can face left and right too, which is covered in the conics playlist also under Algebra 2). Here, we begin with factoring some harder trinomials using the now-internet-famous Berry Method, then mozy on to completing the square, the Discriminant, leading up to seeing them as graphs. Then some transformations of quadratic functions, and a super-intuitive way to learn about Quadratic Inequalities, not done in the books.
 

Helpful tips:
