Algebra 2 - Analyzing Quadratic Functions (part 2)

Who says the sequel is always worse than the original? Not this time. In our continuation of analyzing transformations of quadratic functions, we take it a step further, and use completing the square to get our equation into vertex form. It's a high level completing the square too, using factoring, with leading coefficient. These polynomials have nothing on us, so welcome and join our fun learning! YAY MATH!

Last year, your videos helped me pass one of the hardest Math classes of my life and I passed! I was able to transfer to Culinary school to pursue my true dreams and I really enjoy my new school now. Thankyou so much. Your vids change lives!

[@umaungmaunggyiumaungmaungg2560]

Thank you.

[@gameblamerfan]

Math seems like fun ^^ I wish I had you as teacher

[@googleuser9660]

Thank you SOOOOO much for these videos! I learn more here than in my own class! LIFE SAVER!

[@PedroGarcia-tz3lr]

You are unique. Thank you.

[@simplehumancomplexambition9884]

11:52 "it was a hand". That one was funny

[@sunny.n9317]

i was almost to drop the course while i was the top student over the past two semesters but with u im ok now thx thx

[@rrrrrr-ob3fw]

Thank you yay Math! You help me study.

[@cain1830]

You are truly outstanding! Really.

[@yaimalopez9901]

taking an online college class and this has been a life saver ... thanks :)

[@luciusirving5926]

Another good job! :)

[@JohnDoe-gk5xj]

Please tell me where did the positive 4 come from?

[@Ekaterina58]

What happense in insted 16x you had 18x? In other words what shell we do when you try to write half of b, which will be 9 and undevideble on 2?

[@gdkiantheboss7664]

You can still divide 9 by 2. It's okay if it has fractions.

[@margiebacsierra3499]

Hello, I appreciate your video, but I have a question on why you subtracted 32 at 4:34. Why couldn't you add 32?

[@linahdiaz8704]

Cause you have to cancel it and you cancel by subtracting in both sides

[@marias5149]

Dandy E? I think that's the name? Is so chaotic no matter which student it is and I think that's amazing. The sass is wonderful XD Also, super helpful video! Thank you so much!

[@Matthew_Mayoglou]

I had a hard time with math in school if I had you I would of been a math teacher

[@robertahdoot]

That's super kind of you to say, Matthew.

[@Ekaterina58]

Hi, I have the same kinde of question again: what can one do if there was 17x insted of 16x? I shell be very thankfull for your answer.

[@cristianmolina6306]

Ekaterina Tavadze Melin Grouping (doesn't work with all equations), depending on the exact equation using the quadratic formula might be easier.

[@josher14xx21]

Confused on why -3 multiplied by the +4 gave you +12, shouldn’t it be -12?

[@teres1523]

(X+1)^2+(Y+5)^2 =25 How do you get the pair and say if it is a function or not from this? Where can I find this lesson and also: vertical stretch, reflection, aces of symmetry, even odd functions, graph square root functions. I understand your way of explain , I have being following all your classes. I hope you respond!!!!!

[@funchanel4all869]

I follow u ,you are genius prof. Let me yr frind Regards Engr .Gamal [e-mail] Egyptian engineer

[@olgakasianova6581]

He's fun. I don't even know why I'm watching this video. I shud be studying for my midterm in diff.equations lol

[@tjbjsb]

I know where the 32 came from, but why add and subtract on the same side?

[@dalilaguillen7]

tjbjsb I think it's because the rule of what you do to one side you do to the other can't apply because we want y to be alone

[@ti84satact12]

Because if you add 32 and subtract 32, you really haven't changed the equation, although it helps get the equation into a form that allows you to complete the square..

[@royalwilson6640]

OK in the answer (4, 49) where did the 4 come from ?

[@hello123s]

From ua mum

[@AddyOnGuitar]

Whats the difference between y=ax^2+bx+c and 0=ax^2 +bx+c?Please answer this.Anyone?

[@terroristtt7011]

10:33Waht a great thumbnail😂😂

[@Ricardo12959]

Respond angry to the students, that would make it fun >)

[@hello123s]

Yeah.. A fun prank!

[@thatdude8884]

I'm still confused how you add the 32 to the equation

[@fairyyoongi]

it''s really 2(16) therefore 32

[@AlejaXo]

i need help with problems like this one ... anyone ?? 😭😭😭 Y = 3x'2 + -20x

[@gdkiantheboss7664]

Complete the square like what he did in the video

[@AlejaXo]

[GD]Kiantheboss passed my class with a B thanks

[@gdkiantheboss7664]

Guadalupe Ambriz nice

[@jayachelliah4067]

Not possible as it is not a parabolic curve but a straight line... I hope this is right
