    I am in my mid 30s, trying to go back to college for nursing and I have to upgrade both math and chemistry in order to apply for the program. I have been doing review beforehand because they aren't my strong subjects. You have been my teacher in both subjects, I like the way you explain things! Thank you

      Good luck! Although I am of the belief that nursing does not need a college degree and would be better going back to the apprenticeship system that was used until the last few decades - of course, there isn't as much money to be made from students that way...

    The part of "time 1/2 and square it" is the eye of the needle, which has stopped millions of camels to get through it. Sir, you have done a great job to open the gate to algebra heaven.

    Best math videos. Thank you. It is fascinating how the process of dividing by 2 and squaring makes the equation workable regardless of values that are not factorable.

    This man has succeeded in elucidating the fact COMPLETING OF SQUARE is still a waste without factoring....
    We do🔥 COMPLETING of SQUARES only for us to be able to factor again🔥

    Wow is all I can say. Great lesson. Thank you so much.
    My brain has been in melt down over x^ + (x+1)^ = 25. I got it down to x^ + x = 12,
    but that is as far as I could go. I followed along w/paper & pen, each step.
    Starting at 10:15 - 15:25.
    My answers are 3 or 4. 3 solves for my x
    Yes, it's the old 3,4,5 triangle.

    How does it work with this one. Y^2 +3y -10=0. I don't seem to get the right answer. Get (y +3/2)^2, which expands to y2 +3y +(3/2)^2 -10 =0+(3/2)^2.
