I would use this site to graph polynomials. You'll find out sooner or later that mostly everything about high school math is about "how would I graph this equation?" There's two main parts about polynomials you need to know about. One, the highest degree polynomials indicates how the ends of each function go. Even, both ends go up. Odd, left down and right up. Second, are the basic graphing properties, reflections and translations. Once you get those, you should be able to recognize and differentiate the different graphs. Next, it's all about finding the number of roots or numbers that will give you zero when you substitute for the independent variable. To figure this out, you will need to learn about the rational root theorem and apply a bit of guess and check. And that pretty much sums up all you really need to know about polynomials. How to graph and how to find the solutions to the equation. Later on in calculus, they will teach you that being absolutely precise is too tiresome and that being close enough is okay. And the question will then be "how close do you want it?" Where you can soon approximate values and roots using linear equations, and functions using polynomials.

Check out PatrickJMT on YouTube. I went back to college after a 10 year break. Took pre-calculus through calculus 2. His videos are what got me through those tough classes. His explanations of the material are straightforward and very easy to follow. Many thanks to PatrickJMT.

Exactly what I am doing. Thanks for this suggestion. I've been trying to will myself through them, but honestly I don't want to just get through the math I want to actually be able to use it for practical purposes. I tried to take an MIT Python class at edx and got humbled quick.

My go to response of Khan Academy was already stated so I have nothing to add except... Polynomials are pretty tricky, but, you got this, OP.

Not sure if I'm late. Have you seen mathbff? https://www.youtube.com/user/mathbff
