Completing the Square (1 of 2: Explanation)

[shalersasandre]

You really are an engaging math teacher, and certainly dont fit the stereotype of a math teacher!!! Your youtube videos are so much more intresting than my coaching classes or school. Please, do keep doing what you are doing, for atleast I, for one am really grateful. And i am sure there are many.
Thanks a lot, sir.

This is a much better explanation to what I got in highschool. Great Job

I am a 11th student (in India high school is 11th and 12th), wasn't able to understand this method from past 5-6 months, but this 1 video did something that no other teacher did in such a long time. thnx

1:56 "But 1 and 7, at least last I checked, 1 and 7 do not add up to 6"
Good point

It seems such a tragedy that someone’s ability to understand something - and it doesn’t have to be mathematics - can come down to the lottery of who teaches them. Something else that baffles me, is why there is such variation in teaching ability. This guy is clearly off the scale, at the other end was my history teacher, who sat at his desk reading from the text book - word for word - and we wrote down what he said - and that was every history lesson we had with him for two years!

[Crucizer]

the same method (splitting the middle term) but without using the trial and error method but using maths. He actually solved the same example you chose to make the students understand that splitting the middle term method is not good enough.

if you could work for khan academy it would be great

surely (x+7) (x-1) ???? for the quadratic at 2 min 13 secs ???

[GianlucaBerger]

I have a quiz on this, Friday and this helped so much. Thank you

[gavinwhitford]

You are by far the best teacher I’ve ever seen teach it’s honestly incredible

Mr. Woo you said at 5:55 "all quadratics all of these guys they all end up with tow solutions don't they", what if the quadratic is x^2 -10x + 25 =0. Then X would be 5 only, which is only one solution. Is this a special case or does it still have two solutions like 5 + 0, 5 - 0 etc?

7:05 He says that those two numbers will give the results of _ + _ = 6, but
(-3 - sqrt(2)) + (-3+ sqrt(2)) doesn't equal 6. It equals -6.

Brings up "perfect square" - 2:42
Explains and demonstrates at six:13 of _Completing the Square (1 of 2: How does it help?)_
Very simple, but with so many new concepts at once some can get lost

[cowboybob]

1:35 - Should this work with the answer derived at 8:04 ?
He says "like you predicted"
But the prediction (as I see it) is multiplication
And his method ultimately used addition 8:04

[zakariaibrahim]

Why did the two solutions multiply to 7?

[WhatsPopping]

Anyone know how to do completing square for xsquared + 8x

[gamingshortswithdj]

So engaging and now i finallt understand this thanks so much!!! I'm having fun learning and its a weekend....

[camembertdalembert]

"1 and 7 do not add up to 6" !!! this is incredible.
