  1. In the last 2 it would be shorter and easier to divide all the terms by the coefficient of X^2 first, and then proceed from there. Ex. 3x^2 – 5x -7 = 0 –> x^2 -5/3x – 7/3 =0 –> x^2 -5/3x +5/6 =7/3 –> (x – 5/6)^2 = 7/3 + (5/6)^2 –> (x – 5/6)^2 = 7/3 + 25/36 –> (x-5/6)^2 = 109/36 –> Sqrt (x^2 -5/6)^2 = Sqrt (109/36) –> x^2 -5/6 = (sqrt109)/6 –>
    x = 5/6 +/- (sqrt 109)/6

  2. I was so damn scared of completing the square watched 2 videos asked my math teacher to explain didn't understand a damn thing but my god you just made it look so easy now I have understood everything thank you very much!!!!!!!

  3. 21:48 I believe there's an easier way of solving this (at least easier for me)

    3x^2 – 5x – 7 = 0
    (3x^2)/3 – (5x)/3 – 7/3 = 0/3
    x^2 – 5x/3 – 7/3 = 0
    x^2 – 5x/3 = 7/3
    x^2 – 5x/3 + (5/6)^2 = 7/3 + (5/6)^2
    (x – 5/6)^2 = 109/36
    x – 5/6 = ยฑ โˆš109/6
    x = 5/6 ยฑ โˆš109/6

  4. The first example make no sence, in second line you add 2^2 to both sides and in third line you exclude 2^2 on the left side.
    The true approach should be to use your technique but instead of adding 2^2 on both sides, just add it on right side or substract from the left side depends on the qustion

  5. Holy fidddlesticks! This really did help me on my super hard math exam! Thank you Organic Chemistry Teacher for helping me on this gilly golly difficult exam! I was able to get a A+ on my exam and my parents won't put me in the basement again! Hip Hip Hooray
