I want to thank you from the bottom of my heart! I passed my Algebra class with a "B" I couldn't have done it without you. God bless you greatly!
A B? That's awesome! Congrats Nicky and thanks 4 sharing!
I just got a 92% on my algebra test! A 92! It was almost all quadratic equations. Thanks to you, I finally "got it." A 92!!!!

Ok
Congratulations Beryl! 🎉🎊👨🏾🏫 (A little late, but here I am😎)

Smh
Exactly! 😔
Hey mr whitt! Last time we talked I said I was off to college and I am here. Instead of a nurse I am going for early childhood education and special education. Once again like the GED you are guiding me through this math!! Thank you, I recommend you to everyone I know!!
How to remember the quadratic formula. (Search: Awesome way to remember quadratic formula)
A "negative" boy "couldn't decide" if he wanted to go to a "radical" party. "Being square he decided "not to go" and missed out on "4 awesome chicks" the party didnt end till "2am"
It makes not sense but it helps me remember so it works!
Cadence Smith awesome!!
It is a shame that you don't teach in a college somewhere! I would be honored to have you as an instructor in the classes that I have been taking, because the teachers today are LAZY! They just don't teach anymore! Your video had (6) examples and each one was different, which has given me a better under standing of the quadratic equations. P.S. Ms. Shirley is the best!!!!!
I was struggling in my math class. My professor records video's and then posts them. He just doesn't go into detail like you do. I literally just discovered you my last 2 weeks of class and I'm so upset that I didn't find you sooner! The last video I watched (square root property) helped me understand the material. My professor skipped over posting a video about it, so I guess he expected us to learn that on our own. Once I watched your video, it blew through the homework in a matter of minutes where normally it would have taken me over an hour. Will definitely be using these video's when I get into my other math classes! Thanks for helping me pass my "remedial" math class!! I put remedial in parentheses because there is no chance that this is remedial. Now on to my College Algebra and Business Statistics math classes!!!
When some of my classmates are gossiping to me that our Math teacher is explaining poorly or too fast, I recommend them to watch FortBend tutoring and they loved it! XD I'm living from the other side of the world so we just got back from school about a month ago and had a new Math teacher which is still adjusting from her job so for the meantime, I'll go and learn Mathematics from you Mr.Whit!!!
+Aldjeus Valenzuela Thanks so much 4 sharing Aldjeus! I really appreciate it! Tell your classmates I said hello!
Fort Bend Tutoring Will do! They love you and your content by the way :D
same here
I literally figured out how to do this thanks to your videos in about 10 minutes when I still couldn’t figure it out from my professor after hours of classes. Thank You!
My boy! I was gonna be tested on this today but a fire alarm went off and our teacher moved the test back one day. Took advantage of my good luck and this video helps so much! Thanks man, you doing good fam.
Happy 2 help Sam! Good luck kicking butt on that test!
i have an exam tomorrow and i believe there will be quadratic equations and this was really helpful as i have never learned them before. I thought this was going to be the hardest thing to learn but with your help i finally understand it. Bless your heart!
+Ahmed Wali Happy 2 help Ahmed! Good luck on your exam tomorrow!
My goodness i have been trying to understand this formula and no luck until now!! THANK YOU SO MUCH!!!!!
Missawesome55th You're welcome! Happy 2 help!
I knew I was doing something wrong and couldn't figure it out until I watched this video. You made it so clear that "I got it"!! From the heart, thank you so very much
+Beryl Moreau You're very welcome Beryl! Happy 2 help!
Oh no! You put the negative solutions first! My faith is shaken. LOL, seriously, thank you for the straightforward approach. It's very clear and I can usually figure out things on my own if I have a question because of the way you teach.
EXCELLENT !!!....was taught in a way no other video could....Thank you.
Want to give a big thanks to You because I earned a 90 on my test for the solving systems of Equations, the elimination and substition method, I always come here first when I need extra help, You break things down and make it so clear. Now this video well help me on my last section in Algebra 2, next up in Radical complex numbers...also will give a donation to your channel I appreciate your time and help.
Thanks so much for the update! It's great to hear when our videos are helping students like yourself that have a desire to learn and succeed! Congrats on your 90!
U are such a good teacher.I understand this a lot more than other videos I watch.Top number 1!!!!
omg I'm preparing to take the compass test for entry into college and this had been by far the easiest quadratic tutoring I have found you have explained it to the t I am feeling more comfortable now that I've watched your vids. at my age I didn't have to learn this stuff, so thank you I will be on your page all weekend I test on monday.
That's wonderful 2 hear Ka'Miya! Good luck on your upcoming Compass exam and thanks 4 watching!
Thank you
can i just say that as i get older (mid 50's now) i'm losing my brain power,. not only did i forget how to solve the problem, i'm getting to the point where i don't remember that i even knew it at all! so in order to hopefully re'hydrate' my brain, i'm going through all these - so thanks - great instructional video!
Thanks 4 watching! We're very grateful 2 be able 2 help you get "hydrated"! :-)
I understand! I'm 62 and taking college algebra. The brain doesn't work so fast!
Mr. Whitting is a great teacher I have learned with understanding so quickly, so thank you Mr. Whitting
Happy 2 help Phyllis! Thanks 4 watching!
Keila Calles In problem #1, (-5)² = 25 because (-5)² = (-5)(-5) = 25. When multiplying, an even amount of negatives will always yield a positive result.
Fort Bend Tutoring Thank you so much!! Now is so clear for me....Thank you, your videos are really helpful. I appreciate your answer :-)
No "problem"! ;-)
Thank you Mr.whitt now I finally under stand the quadratic uquation Im ready for the exam
Good luck on your exam Francis! I’m rooting 4 you! 👨🏾🏫😁
Thanks for the feedback! Keep the comments and constructive criticism coming! It's really helpful!
Thank you for sharing and taking time pass it on your knowledge!
I never went to high should and still is I have this mathematic problem solving in my head that I've always been good at, but you are making me great. Thanks
Happy 2 help Patrick! Keep working at it and you’ll get even better! 👨🏾🏫👨🏾🏫
I am so grateful you make these videos!! They are clear, easy to follow, and entertaining. I am passing my math class because of you😁 Thank you so very, very much
Been watching your videos for years brother... Great job...
Thanks 4 the support MDU NTR! I really appreciate your patronage and feedback!👨🏾🏫😁
Hi Fort Bend Tutoring even thou Mr. Whitt is having a hard time drawing braces. For me his drawing of braces is fine and cool also. And thank you for this tutoring videos it helps me in the Exams :)
This is the first video covering this topic that I thoroughly understood! Thank you so much✨!!!
Happy 2 help Kiwi! Thanks 4 your feedback. I really appreciate it! 👨🏾🏫😁
Thank you. The problems were explained step by step and easily understood. You also wrote very neatly. I learned a lot.
My pleasure Valerie! However, I would appreciate you telling the truth in the future or perhaps you should seek out a seasoned eye doctor. There is no way you watched this video and thought my handwriting was neat! LOL Thanks 4 watching! :-)
Outstanding tutorial. You are an excellent "explainer" and your delivery is impecable. Really well done!!
Thanks 4 the feedback and support Roberto! I appreciate it! 😁👨🏾🏫
Everybody in my College Algebra class is struggling. I made sure to tell them all about you. My husband kept saying you need to find out how you can send money.Cause i've been talking about your videos so much!!! I cant even believe how simple you make stuff.you need to come to College of the Mainland in TexasCity.
+Shana Mark Sounds good Shana! I use to teach down the street at LaMarque High School! You can make a donation using the following link! Thanks 4 sharing [fbt] videos with your class. I really appreciate it! 😄 www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=P5DTKAQFCF7NQ
what years did you teach at Lamarque?I went to Lamarque middle school and 2 of my High school years, but I graduated from Hitchcock High.
It was the 1997-1998 school year! Goooo Hitchcock!
I finally got it. Thanks for doing more than one problem
Our pleasure Merri! Thanks 4 watching!
Thank you so much! Your videos has been a blessing to me! Thank you!!!!!
Finally I find a video that explains the steps slowly thank u so much
You're welcome Bre! Thanks 4 watching!
Love the intro. Not sure what accent that is, but the part about speaking English is hard cracked me up.
This video is really helpful...the best so far.
Thanks 4 watching Aira!
Man, Thank god you are there thank you very much i passed my exam for in return i will subscribe😀😀
Congrats on passing your exam and thank you very much 4 subscribing! 😀
You really simplified this so easily! Thank you!!!!!
You're very welcome! Thanks 4 watching!
MR.WHITT.I AM THE IMPERTOR POLYNOMIUS.YOUR VIDEOS ARE MANNA FROM HEAVEN.I HUMBLY ASK FOR YOUR GREAT AND DIVINE WISDOM.COULD YOU USE THE COMPLETING THE SQUARE METHOD AS WELL AS THE QUADRATIC FORMULA FOR ALL PROBLEMS OR ARE THE METHODS FOR SPECIFIC PROBLEMS???
🤣Happy 2 help Nathaniel! Both the quadratic formula and the completing the square method can be used to solve any quadratic equation. The square root property and zero-factor property are for specific problems! 👨🏾🏫😀
LOL...it's bc you're left handed! I am too! I do pretty good with the left bracket, but my right bracket sucks! And thank you for all of your tutorials, they've helped me tremendously!
You're "right" Camanche! You're welcome and thanks 4 watching!
Thank you so much, from Australia!!
This was the most helpful video. thank God!!!!!
Happy 2 help! 👨🏾🏫😁
Thank you so much for the tutorial! It made the quadratic formula sooo easy! Thanks!
My pleasure! Thanks 4 the feedback!
This video was absolutely phenomenal!!! I can see clearly now. lol. Thanks, Mr. Whitt this is just what I needed. Keep up the good work you have made a difference in my learning.
hahahhahaah omg the intro was so funny.... i love the way u teach sir .... good luck and yeah i love old school too
Thank you for making it so easy! You are a great teacher!
+jojo9475 You're welcome JoJo! Thanks 4 the compliment!
That outro was HILARIOUS!!! My question is, in the last few problems, there wasn't an ordered pair or are the solutions the ordered pair?
None of the solutions are ordered pairs. We're giving you solutions sets. A set of values that will make the original problem true. The answers are actually the x-intercepts of the quadratic equation. So a solution of {-2,4} has ordered pairs that are (-2,0) and (4,0).
Fort Bend Tutoring Thanks so much!
I’ve seen many descriptions of how this is done but this is the best one yet. Although you’re kind of fast for a person like me meaning someone who learns math slowly, I believe you are the best math teacher on the Internet and I’ve seen a lot of them. Thank you very much!
Once again. Very good examples!!
Great feedback!
You are great teacher and I love your accent
thank you sir once again..this tutorial keeps rocking..
Thanks 4 the support Musuka!
Thank You For this !! Now I understand it clearly . I hope I will get a perfect score in my assignment
Good luck and thanks for the comment!
Your Welcome . :)
THAT INTRO IS THE BEST THING EVER
Lol! We agree! Shirley Q. Liquor is amazing!

Thank you for helping me learn
+Rosie Balderas My pleasure Rosie! Thanks 4 watching!
Real good Mr Whitt.
+Rod Galloway Thanks so much Rod! 😁
You're videos help me a lot.. So thank you so much! Now math is made easier with your vids. I enjoy watching them =)) the intro pls.. =))
I was having trouble understanding this formula. thank you.
You're very welcome! Thanks 4 watching!
Thank you sir! awesome job!
I appreciate it! Thanks 4 watching Jonah!
I really enjoyed the video. I found it very helpful, and I will use all the advice given. I was hoping the professor would go one step further. I would have appreciated a quadratic equation using the quadratic formula showing two forms for each solution. Wherein one of the forms would be an approximation in decimal format. Thanks.
Thanks 4 your suggestion Elsie.
thank you for breaking it down and simplifying. :)
+Frenchie My pleasure Frenchie! Thanks 4 watching! 😊
the intro is so hilarious"are you having difficutties"
Lmao Thanks!😊
Great work! This lesson is really helpful....kudos.
Thanks 4 the feedback Abiodun!
Thank You So Much! Love you
You're very welcome Hamail! Love you 2!
I've learned more from watching you than my professor thank you
Thanks 4 letting us know Rachelle! We're happy 2 help!
If i do quadratic equations with one variable and use this video will i still know how to do it if it only has one variable?
The MC is killing me at the beginning! lmao...I love it though!
Camanche The Embalmer LOL Glad you liked it! Chuck Knipp's "Shirley Q. Liquor" is awesome!
lol...Im gone need soma that in my life!
GREAT TEACHER.
Thanks 4 the support Siragan!
You have the best videos! They help me learn and make me laugh. Thank you so much. I would be failing if it weren't for these tips!!
I need help with y=4x^2-9 using quadratic formula im stuck on 0 +- square root of 144 divided by 8
I love all your vidros wish you the best sir
Thanks 4 the support Vince! I appreciate it! 👨🏾🏫😁
You videos are very helpful to meeee. Whoo life saver haha thank you very much
You're welcome Antoinette!
thanks for this wonderful exlpanations
+GOODFELLOW MWANZA You're very welcome! Happy 2 help!
Mr. Whitt, Hello! Could you please make a tutorial video about Quadrilaterals? It is currently our Math Lesson. I would want to learn it beforehand. Thank you very much!
My teacher said the first value of x is gonna be x sub 1 and the second value will be x sub 2. We call the brackets, where you’ll put the two value of x, the set solution. The x sub 1 and x sub 2 can be interchange especially inside the brackets.
Cool Lessa! Thanks 4 sharing!
Seriously thank you!!!!
+Luzita van Dyk You're very welcome Luzita! Thanks 4 watching!
thanks Mr- Witt that's was very very helpful
Awesome Haider! Happy 2 help!
THANK U SIR!!!!!!!!
bless your heart
Thanks so much Jewel! I really appreciate it! :-)
Just like that. Thanks for the review Mr. Bend.
I mean Mr. Whitt, not Mr. Bend, though I'm sure he's a fine fellow too.
+Rodney Bentley lol Thanks Rodney! I'll thanks them both 4 you! ;-)
great video and easy to understand , thank you
You're very welcome! Thanks 4 watching!
are there actually teachers like this in fortbendisd ?
Maybe, I use to teach for Fort Bend ISD years ago.
oh i thought so my teacher dosnt teach
You made it easy. Thanks!
My pleasure Miranda! Thanks 4 watching!😁
Excellent! The only thing that I did not understand is why you change the 49 to 7 and took it out of the radical?
Similar to fractions, you always simplify radicals when possible. Check this video out: ruclips.net/video/M_zIjMICB3k/видео.html
question..the part i get stuck on is when you have to set the equation to zero.like in the ex ,2x=4-7x. ..you decided to dd 7 and sub 4 from both sides..y is that ?c an you make a video thoroughly explaining why you subtract or add the paticular numbers please
Natalie 8 In order to use the quadratic formula, you need the values a, b and c from the formula. Finding the coefficients a, b, and c becomes easier if the equation is set equal to zero and in the form ax² + bx + c = 0.
This is amazing doppppppeee
+sai naru Thanks 4 the support Sai! 👊🏾
Thank you very much
You're very welcome Maher! Thanks 4 watching!
Love this
Happy 2 help! Thanks 4 watching!
Thank you!
You're welcome Matthew!
Wow! I really live math ! Ths s my inspiration to do the same thing! Making mathematics videos. Ty for the insights!
Happy 2 help POMMI! 👨🏾🏫😁
Thank you sir this is helpful
This was super useful!!
Fantastic video - thank you. What is that device you are working on? It would make good scratch paper instead of all the paper I go through!
What program are you using to work out your problems? I have noticed you have it on several videos. Thanks!
It is called Penultimate by Evernote (an older version).
you guys are awesome
So are you Benjamin! Thanks 4 watching and leaving us feedback!
excellent learning
OK I'm confused! So in problem #2 C= -4
after you plugged all the values, you simplified and got
(this would be under the radical sign)
49+32... (I get how you got 49 7x7) BUT #1 why aren't we using the - sign before the 4 and even if it's supposed to just stay as "subtract" #2 why did you do 4x2x4 and not 4x2x-4? is't C= -4? Help me Mr Whitt :)
+diane rozankowski I did use both the negative before the 4 and I used the value of c as -4. The product of (-4)(2)(-4) is 32. Because we have an even number of negative values the result must be positive so I focused on multiplying 4(2)(4) which is also 32. ruclips.net/video/HKxFtb28wmo/видео.html
+Fort Bend Tutoring Thanks for the link! I think I'm good now. No more sign questions lol. Thank you very much :)
How would you calculate the 5 postive &negative with the square roots?
You would either write them separately or calculate one with the positive using a calculator and then the other using the negative.
Hello professor do you have any videos on factoring when the a is negative?
Not in a video, but in this workbook: shop.tutormemath.net/product/simply-math-workbook-12
please tell me which stylus and e-board was used
would appreciate it:)
