- 👉Learn how to factor quadratics when the coefficient of the term with a squared variable is not 1. To factor an algebraic expression means to break it up into expressions that can be multiplied together to get the original expression.
To factor a quadratic trinomial where the coefficient of the term with a squared variable is not 1, we find two expressions which when multiplied together gives the product of the constant term (the term with no variable) and the term with the squared variable and when the two expressions are added gives the term whose variable has no power. These two expressions obtained are used to replace the term whose variable has no power. The result is then factored by grouping them and factoring out the GCD.
There are other methods that can be used to achive this including the AC, Berry, Box, Grouping and mental technique. Each way will have it's benefits but it is also helpful to check your answer by multiplying your binomials to make sure they give the original trinomial

THANK YOU SO MUCH i learned an entire unit in this one video that i didn’t understand from 2 weeks of zooms
You made the AC Method crystal clear. For some reason, I was struggling with this concept. I now understand. Winner Winner Chicken Dinner. LOL.
I am currently attending my local community college, where I am majoring in Math. My goal is to transfer to a 4-year university. I'm not a traditional college student. I am 68-years-old, a retired soldier, and a disabled veteran. Current GPA is 3.9. "You older students are so motivated," my professors tell me.
I agree. My older student's are definitely much more motivated than my younger students :)
Thanks for ur service good luck with college!
Good luck, I hope you have since made it into a four year college. I am also in college, and this was helpful lol. Thank you for your service
I want you to know that you just saved me tysm
yooo same lol I had to do this yesterday I was so confused what to do after u multiply the a and c
Brian you should have way more views! These videos are under rated, I would have literally failed my math class without these. Somehow you just make it simple to understand for a math idiot like me. Thanks
I FREAKIN LOVE YOU. I tried the old fashion way of trying to learn this on my own but for the love of nuggets I just couldn’t figure it out. I could have saved hours by just starting with this 5 minute video. THANK YOU SIR.
Jesus christ man you have no idea how much time you've saved me. I've been staring at my text book for 30 minutes, then went on Google where I was only shown how to work out 4 term expressions then I finally fours.
So happy to be there for you!!
Omg you just saved me I’m a freshman In hs and I have no idea what I’m doing and my midterms are coming up so thank you
this guy is probs the best explainer i have ever listened to thank youuu
Agreed. just watched and understood this completly after not having a clue what i was at after 2 weeks of class
Would have failed my test without this I made it into honors algebra which means I take it in 8th grade this was so confusing tysm
YOU SAVED ME!!!! U HAVE EARNED A SUB!!
Thank you so I've been racking my brain for this
This is the best method, the only one that works for me, thanks!
It’s been 6 years and your video helped me so much! Thank you!!!!
Yo dude you explain the lesson in almost 4mins meanwhile my teacher need a half an hour to discuss it btw thank you so much
Thank you ser this tutorial helps me
This video the only i understand more even the example is only one i learn it quickly! Glad i found this video cause i will have a test tomorrow 😭
you just saved me from going to the algebra 1 eoc without knowing how to factor
Thank you so much! I think I kinda understand now! Been absolutely struggling with math lately.
Happy to help!!
Bro… thank you so much. I’m taking algebra 2 online to catch up with my friends for next school year but it’s so unclear they just skip over how to do certain things and this is actually understandable. (I don’t have hardly any algebra 1 skills bc my teacher was a pushover and we also had a sub for half the school year who just made us play battle ship 😐)
i just want you to know this was very helpful
you explained it better than my teacher
Thank you I needed a refresher for geometry
Thanks dude, I needed to review this for factoring trigs. 4 more weeks of precalc to go!
I cannot fathom how easy this was
thank u!! i literally relearned this yesterday but i forgot 💀
I was rlly confused with this and you really helped me. Thanks!
Happy to help
@@brianmclogan is this the fastest method for factoring trinomials?
Hey bro, if some kid one day going with the name dimandous ever becomes successful one day, please just remember that he appreciates you for saving his ass in 9th grade. This definitely saved my life.
Here's some math 2 hour class < 3 minute video. Thank you!
Hehehehh on my perspective you can just directly factor the equation by general trinomial☺
This channel is insane you explained them well and now I gain more knowledge and it made me realize that in Math there are really a lot of method to use
so, so helpful!!! i appreciate you❤️❤️
I just want you to know that you saved me a mental break down😓
Helped a lot thanks!
TYSM! Math ain’t fun till you find how it works
Thank you so mush this really helped me. You are a life saver.
Thank you very much sir grateful for u
You're the best dude, this really helped, Thank you so much!
You are very welcome!!
Omg everything made sense now... you’re a genius...in my opinion 😂
3n^2-15n-2n+10
3n(n-5)-2(n-5)
(3n-2)(n-5)
n=2/3 dan n=5
saved my life thank you!
Please squeeze a plus sign in between your groups. As written, it looks like polynomial multiplication.
raaa i wish my teacher had used this method it's so much clearer
You made it so easy!
THANK YOU!!!
what, this is so easy. why have i been stressing the last 3 weeks of class lmao. litteraly took 3 mins to grasp. tf is wrong with education...
Helped a lot
You make me so happy bro
taught it better than my university professor could in 4 minutes while the powerpoint they want me to watch is an hour long yea right
really helpful
U teach better than my actually teacher
helped me so much thank you!!
TYSMMM MY HONORS ALG TEACHER WAS ON SMTH POSTING LIKE 11 ASSIGNMENTS
Thank you for carry
Thank you very much for this!! It helped a lot
My teacher is so damn bad but u clutched up yet again
What if I wrote -2n-15n? What is the rule in witting this?
with this method it does not matter. You can group them however you want once you've found the two factors. You just want to group the ones with common factors so you can reduce.
Thanks!
Thank you.
You are very welcome!!
The method is great but my numbers were -4 and 6
thank you
Whenever I do this method the last group of parenthesis are still factorable which makes it incorrect. What do I do?
If the last pair of parentheses are still factorable, then find the common factor and multiply it to the term which you factored out first.
thank you.
You are very welcome!!
i like you for this man
I.... Thank you. U gonna save me
THANK YOU
Helped me A lot. Thank you so much!
Can you be my math teacher 0^0
TY!!!
does it matter how where you put the negative 15 and negative 2?
No it doesn't! That's the nice thing about factoring by grouping, you can switch the numbers but you'll still get the same answer, yayyy! 😃 Lol
Ngl, I wrote a computer program for that factoring part.
What do u do if nothing adds and multiplies to ur number ?
then it's not factorable, meaning there is no answer.
When you say grouping do not place the parenthesis around the first two terms and last two terms. That can be misunderstood and is not mathematically correct. Perhaps underline the terms. Just a suggestion 👍
3. -2
1. -5
(3x-2)(x-5) . That's my short method. Any questions. Thank you

Great job
I keep getting thrown off at the grouping part 😮💨 how does 3n2 turn 3n
What happens when your grouping and u don’t match
I have this ridiculous problem. It's killing me. w^2-2w-48. I just hate it so much. It doesn't even make sense.
This is the same thing as 1w^2-2w-48
So here A=1 and C=-48
So then A*C=-48
To factor, there's two things you have to take into account: the B and C numbers.
Here, B=-2 and C=-48
First of all, what two numbers can you multiply together to get -48 (the C)? But also add up to -2 (the B)?
It'd be 6 and -8 because:
6*-8=-48 (the C) and
6+-8=-2 (the B)
So then you'd replace the -2w (the B) with the 2 numbers we just found: 6 and -8
So you'd have w^2+6w-8w-48 and then lastly you'd factor it by grouping. Hope that helps! I'm always happy to help on my channel too. good luck! 👍
I just got more confused
You speak way too fast!
ahem you are in youtube
you can slow down or pause the video, jeez
