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:

  • At the top of each video, you can access that lesson's worksheet and quiz.

  • The worksheet contains the exact problems we cover in the video. Just print the sheet and work along with the class.

  • Take the quiz right after the video, to see how well you learned it.

  • To access the worksheet and quiz at any time, simply pause the video.

  • Below, you also have the option of viewing the same playlist on YouTube.
