    I have watched some of your videos and they are really helpful to me. I am in Algebra 2 and your videos have really helped me strengthen what I know and to remind me of things I should know. If you could like this comment, it would mean the world to me. Thank you.

      @Lin Ku I don't get what is so wrong about his comment. He is just saying how much he appreciates him. Why you gotta be like that? Try to be less mean less time. How would you know if he wants likes or not?

    The video took a while to load and I am in a dark room so when it started I got soo scared because I thought it was the reflection on my screen.

    Brian McLogan is the Scotty Kilmer (auto repair) equivalent channel. Super concise, clear, but then you're left with extra bolts and questions lol. NOT A COMPLAINT, before I start a topic in my online class, I first watch a B.McLogan video to get the concept and then I'm not as confused as I go through the material. Often times, the class teaches a dumber way to do it and I go back and watch it again and use his method. My go to math tutor, you rock !

    correct me if i'm wrong but is the discriminant is 0 the it only means that it has one equal root that isnt necessarily rational e.g. the quadratic (x+√2)(x+√2) has an irrational root but when you expand out and calculate the discriminant it still has a discriminant of 0 meaning this is one that violates ur rule

      Also, he is talking about the discriminant, and has a lot of graphs written there, but the part that I want to know is in small writing, and he stands in front of it while he is talking. I only point that out because it is what every math teacher does. They talk rapidly, they stand in front of the problem, they scribble quickly with their back to the classroom. I think that he could make a better video or maybe combine some videos together to make the point more vivid in my reptilian brain.
