i love you
gosh thank you so much!! i really needed this video, this concept is so confusing but you explained it so well thank you!!
"rutt" is crazy 🤣
UR THE GOAT MR.BRANDL saving me even after high school!
@@sweettea4112 Glad I can help! 😊
Thank you. ❤
Before this I did not understand or even get this concept but after this video it makes me feel so good about it. Thank you so much 💓
Hey man just taking my time to tell you that thank you... you are a saviour and saved me from a test on identifying perfect square trinomials tommorow and i properly understand it now and have no doubts.. you explain it way better than my teacher
Consider subscribed the fact you still know how to not use a calculator is great, A lot of math videos I see they all use calculators
Awesome someone finally without a calculator
Oh nmy day, I've been cooked in my pre-calc class just PREPPING for the subject. THank you so much, all the other videos were about stuff that were unrelated to the material in my class. God bless you, sir!!
I'm coming to my comment just to say thank you again sir, THIS is exactly what I've been stuck on
12 years later and u helped me thx!
Bro is so real for yawning cuz same
@@bastarzgar2217 Needed more sleep at the time. 😂
thanks!!!
ich liebe dich
sigma maths teacher
Needed this for money report! Thanks
6 years later you have the new generation watching this.... Thank you for this Sir
You're welcome! Math never gets old! 😉 Keep working hard! 👍
Wherever you are now just know you are still helping people
Thank you ❤
so funny my lecturer. Your calculation is wrong. x=-7 now all your results are messed up. how you can teach us !!
You're right!! Yikes! I must have been up too late that night! 🤦♂ The correct order triple would be (-7, 9, -9). Thanks for the heads up! I hope there was something helpful there!
thank you king🙏i was overthinking too much just to figure out it was this simple
wow
Saving lives before an exam
I know this is very dumb as I just took algebra last year currently in the 10th grade, but this helped me a lot overall to go back to review the operations of radicals. I just wanted to ask is there such a thing with dividing and multiplying radicals and how would we do it for each of these?
Sure do! Check out my video entitled "Multiplying and Dividing Radical Expressions" czcams.com/video/0Wh5mNGEmBE/video.htmlsi=y1HUJBtqr7IygR67 By the way, there's no shame in reviewing! You've got this! 👍
@@MartyBrandl ❤️
thank you so much! i have a final exam and this absolutely helped.
Thank you so much for this video! I have the algebra regents tomorrow and I was really worried about this but I got it now thanks to you 😁
youre a life saver man thank you so muchh
thanks appreciate it
My brain is advanced even though I am a grade 5 learner I still wanna be learn this type of math. And I do not love math but I do really want to learn this. тнαηк υ.
THANKS
thanks for this
thank you mister Marty Brandl
and on the second I guess it doesn't matter whether you put 3 > b or b < as long as you flip the symbol idk
You've got it! 👍
This is really understandable. I was totally puzzled about this topic until I came across ur video !!😊 Thanks alot it has really helped me🎉🎉
bro thank you so much
He reminds me of Napoleon Dynamite
😂 Thank you?!? 😊
My Soft-Spoken, Humble Self is Good at This
My teacher spent over 5 hours trying to teach my class the basics of this and no one got it, but now because of this video I understood in 3 minutes
Is somebody from 2030?
Hi 2030
Hi 2024 people
Who is watching this video before exam by a day
I am a year 7 high school student and I could not understand long division at all ESPECIALLY with decimals so this video really helped me understand better. Great vid! ❤❤
Man this is 10 years old and still good
Math never goes bad!! 😉
@@MartyBrandl well seriously. Real cool man. I thought since it was old you stopped in som. Actually helped me with school frfr.
why don't you have more subscribes?
Not sure. I guess I haven't really pushed hard. 🤷🏼♂️ You can help spread the word? 😊
LFMAO I HAVE STATE TESTS TMRW AND IM TRYNA REVIEW thanks!
This video taught me how to do this in 5 minutes while my teacher couldn't teach me this in 2 weeks. I thank you with all my heart...God bless you ❤
:)
When in the world would an adult ever need to know this kind of math outside of taking useless college algebra classes lol. But, for passing said useless college algebra classes this is great instruction. Props to the teacher.
theres this question i cant solve a(a³+2ab+b²) can u help?
What is the problem asking you to do? Simplify? Factor? Solve? Let me know and I'll see what I can do! 👍
@@MartyBrandl to tell if the expression is completely factored
@MartyBrandl and if it is factored, could u pls tell me why?
@@hanananahany It is completely factored because there is no common factor for all 3 terms inside the parentheses and the trinomial can't be factored because of the a^3 term. The trinomial would be factorable if it was a^2. I hope that helps! Keep working hard and asking questions! 😊
@@MartyBrandl wellll i failed i got a 2.5/10 but i wouldnt get that 2 if it wasnt for u :)
