Completing the Square to Solve Quadratic Equations

I introduce how to solve quadratic equations by completing the square.
At 12:05 your teacher may be noting that the square root of (x+4)^2 equals the absolute value of x+4. |x+4|=Sqrt(24) then becomes x+4=Sqrt(24) and x+4= -Sqrt(24).

It's awesome to hear that my video series is making that math transition easier for you! It's a giant step to take going back to school at any age, but one that will never be wasted! I'm glad you found my channel so useful and I thank you too for supporting by subscribing. I do love what I do and viewers like yourself are why I continue to try to groW my channel. To get the word out that "FREE Math Help " is available for everyone, everywhere at any age:)...so please help spread the word:D

I have two videos of graphing parabolas, the other is graphing in standard form. The vertex will be your max or min depending on if the graph is opening down or up.

Your videos have helped me succeed in class greatly. You have such great videos and I enjoy them. You make math fun and deliver detailed explanations and do examples correctly, and I enjoy them.

I can't take all the credit…it's teamwork…YOU find extra help on YouTube, I'm there to supply it, YOU have to watch it and learn it, and I'll be there to give you the extra help you need:)…what a TEAM!!!

…guess you'll just have to move to Florida or just keep watching me on YouTube and sharing with your friends and classmates:D

Divide everything by 2, add 6 to both sides, and continue like I taught in this video.

Awesome video series! Thank you for composing these for people like me, who are trying to go back and learn math as an adult. In my youth, I took education for granted and thought math was stupid. Truth is, I was naive and, now, I'm trying to right that wrong. It would be far more difficult without the dedication of professionals such as yourself. Again, thank you!

[paholasaud]

i've failed my last 3 maths tests and im really struggling so i decided to check you out and so far i'm absolutely ADORING your videos !! thank you so much !!!!

Yup. In Geometry 380 we are graphing conic sections and ellipses. Excellent to be back on your channel reviewing this material. Thank you for acknowledging that conic section problems need this too! Thanks!

So glad to see you see you mention order of operation when using a calculator. I see students who make that mistake often when squaring a negative number.

[profrobbob]

:D Doesn't drive you nuts when you correct them like 20 times and they keep making the same mistake! Thanks for watching and the nice comment.

i started watching your videos today, honestly they help alot and its actually really entertaining, you have alot of charisma and I like that.. I was wondering if you had a video that teaches ecuations of the second grade with examples like this ¨x² - ( t+v)² = 0¨
if you could you please leave a link or a response how to solve questions like that. Thanks

[jordanperez]

My teacher pulled up a video of you during my Pre-calc class today, everybody was like "Man he's good!". Hopefully that will equate to more subscribers! Thanks for what you do.

After 0:04 I'm debating whether I should even watch the video. Why can't people just teach math without acting like an idiot?

[profrobbob]

Are you just working with quadratic equations? You could look up Graphing Parabolas with Vertex and Intercepts.

[profrobbob]

Which of the three variables in your equation do you want to solve for?

[djqui]

I thank you so much as you have probably made my grade get to the best it can be please keep what you're doing and I thank you so much.
Ps, why couldn't I have got you as a teacher? Im in North Carolina and my teacher sucks

[georgesadler]

Professor RobBob, thank you for another awesome video/lecture on Completing the Square to Solve Quadratic Equations. This is another method that students can deposit in their toolbox for solving Quadratic Equations in Mathematics. There are multiple ways to solve Quadratic Equations.

[Traketo]

Thank you ProfRob...once again. BAM!!!

[ownleewunful]

Definitely helpful... Thank you, this is the 2nd Chapter I've depended on your videos for my intermediate algebra class lol.

[povang]

very helpful. i was wondering if you have a lesson on radical expressions and complex fraction?
