    The textbook I am using just launches into synthetic division and the Remainder Theorem with no explanation and no lead-up. At this point, I am just using the textbook as a question bank and a guide of which topics to cover. This channel is doing the real teaching. Thanks Eddie Woo!

    My textbook have just rules and rules. No explanation. And my teacher also lecturing the rules that written on my textbook. But this is called the real teacher.

    this is so helpful!! I'd completely forgotten this during holidays and uni uses this theorem a lot since we can't use calculators in class. Thank you!

    As far as cubics go, I love depressing them, or using the discriminant for a cubic. It's just really fun. For quadratics, I discovered an expression on my own for factorising ANY quadratic:
    (1/4a)(2ax+(b+S))(2ax+(b-S)) where S = sqrt(discriminant)

      do you have a blog post for proof of that? It is difficult to read your equation in this format

    Pls how can you find the the remainder when given a divisor of x^2 - 1 and a dividend with a highest degree of 4?

    It should be (x-3) at the end there, not (x+3)

    But wouldn't that mean that we are dividing the polynomial by 0?
