Yes, the quality needs improving. Over the next few months I will be redoing the ones with poorest quality. I also did cut down the format so that they were of smaller size, but UA-cam has now increased the size that your files ca be.
You're correct, virtually no one uses this to solve quadratics if they have been exposed to the quadratic formula. However it is still very useful for graphing things like parabolas, ellipses, hyperbolas and circles. Such as in graph: 2x^2 -14x + 7 = 0.
@UltimateitemHacker Yes, you are absolutely correct. The only time I use completing the square is when I am graphing. For quadratics, I use factoring or quadratic formula, (or the look on my neighbour's paper method). You do need to know this though, if you want to show students how the quadratic formula was derived. Thanks for your comment.
thanks man you helped me alot, i had a as maths test on monday, and if i didnt pass i would have got kicked of the course.... thanks alot for the help. i will sub and rate you video too, thanks keep this up..
Yes, you do. The problem is that completing the square is a long method that has many areas where errors can creep in. Thus, it is not used so much, instead, the quadratic formula is usually used. If answers are not the same, then an error has been made. I do use completing the square to graph ellipses, circles, parabolas and hyperbolas though.
I think you should create like playlists, it would be eaiser to review and find your videos if they were put together in one playlist, for example; A quadratics playlist, that would help! Just throwing ideas around! :)
I really appreciate what you do here on UA-cam, keep it up! Try to focus your camera a little more or improve the upload quality. Do you perhaps convert the video files to a more suitable format and your videos lose quality?
Yes, but if it can be factored, that is quicker. Completing the square is the slowest way to solve quadratics - in fact it is used to derive the quadratic formula, but completing the square is needed in graphing conics. If you know factoring and quadratic formula and how to use a graphing calculator, that is all you really need.
I loooooove your videos. They are so simple to follow. My only problem with them is that they are not high quality. I can barely make out what you are writing.
These lessons are great, and I'm really starting to understand. But the quality is a bit off putting. Is there a possibility for a new camera for future videos?

You make everything seem so simple, thanks for sharing this gift with us !
I love the easines you have for teaching such dreaded topic... I love your videos ...Thanks
dude this is wicked kool, ur awsome yo i understand completely. u explain in every detail.
Thanks for all your help! Cramming for a math final sucks!
you are soo much better than my math teacher :)

thank you so much, my algebra 2 teacher sucks ass at teaching this. you saved me

yeah that would be awesome! i was looking for playlists actually lol
these videos are awesome!! :)

Good to hear. What will you be covering next in your videos?
You're right, it is grainy. I will redo this in larger printing.
I really appreciate what you do here on UA-cam, keep it up!

thank you so much
it really helps lots

thank helps way more than reading a text book
weeb

You divide the x^2 number by whatever is infront.
2x^2 + 8x +8
Would divide by 2
x^2 +4x +4 :)
hey thanks for that good video
on the 2x^2 +12x+7=0 "what if the leading coefficient is an odd number that won't be factored out evenly?" Say like 3x^2 -2x-2=0
Plz! try an upload a vid with diferentiation and integration
But if you have no calculator completing the square is easier, plus i personally feel a greater sence of accomplishment completing the square
Is that a L ... or a zigma .... lol Just kidding. Good stuff this cleared up my question.
I'm sorry, I don't hear the whistle. Maybe, try listening to what I am saying, rather than, how I say it.
add &fmt=18 to the end of the url to hear!!!
This only works with even numbers???
he does aswell, but there is no whistle!
Shows u how to do odd numbers 7:35 onwards
Yes great video. Now quit complaining
i dont think so.
ya..bad mojo...i mean bad recorder...zero star....
