    At 5:42, the restriction should be x can't be -3!!

    you teach well and have a great site. you should definitely cover functions & adv function in its entirety if you haven't already.

    6:38 Would it work to take out 3x from the numerator instead of only taking out x?

    why can you not take out 3x on the last rational expression question in the numerator?

    In problem 3 why only take x but not 3x ? with 3x it works it will give us -------> 3x (3x^2 - 4x + 2) can I use your method as an alternative to polynomial long division ?

    Do you factor out Least Common Multiple (LCM) or Greatest Common Factor (GCF)?

    I have another question is the quadratic polynomial roots are imaginary or complex roots. Is their another method to find the roots instead of Quadratic formula ? For example, what are the roots of this quadratic polynomial: 3x^2 - 4x + 2 ?

    You got the #3 wrong. when you factor the numerator is 3x (3x^2-4x+2)/2x

    No, he didn't get it wrong, he got it right.... whether you factor out 3x, or just 3, or just x, whether you partition the trinomial into 9x^3/2x - 12x^2/2x + 6x/2x and simplify, you will get the SAME RESULT. You see, in math there are many different ways to solving problems and arriving to the same answer. Nonetheless, no matter how you solve the answer, if you follow the steps correctly you will get the same results... that's what makes math so reliable.
