- 👉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

Lol fell asleep and heard him say "did you see what I did John?" Yes I did.
LMAOOOO
bro i know a jonathon yip but i misread your username, freaked me oht for a second there
Lol
Thank you! I havent factored in sooo long and now I am in college precal and factoring is required for almost every calculation. Great review, thank you again.
Happy to help Denisse :). Keep working hard
I wish you were my teacher I literally go to school, listen and then just look up your video and re test how myself cause my teacher doesn’t explain it enough

What grade y’all in ??
@@DavidGarcia-cg3bq bruh I am in 11th grade and I watched this like years go for my test now I am showing this to my brother brings back memories good ones
i wish teachers in my school taught this way. just getting papers shoved in my face and having to cheat for a passing grade.
Thanks so much for the help. I struggle following along with my teacher and you helped me achieve what I needed to do. After all, online school is hard during covid-19.
@Leeham Hannah no your okay 👍 good luck btw :)
Keep doing these videos they help out qlot!
You are honestly so helpful thank you
Taking honors classes aswell?
@@WeluvOwen yup haha
same
I'm very late to this video but this is the most helpful factoring polynomials video I've come across after suddenly having to factor in a class where my brain has deeply buried all that factoring knowledge, thank you
You need to un-bury your factoring knowledge -- because once you're introduced to it -- you'll use it all the time. It's considered a basic math skill.
Thanks so much for the help this definitely improved my confidence on solving decomposition polynomials :)
Bless you Brian and the box method
You are actually saving my math grade. Thanks for the help.
Thank you sir, you’re a life saver
Thx so much this helped me alot
Thank you sm I finally got it by myself!!!
Thus helped me so much ty
5x9=45=15x3. Hence factors are 1/5(5x-15)(5x-3)=(x-3)(5x-3). Hanse x=3 and also 3/15=1/3.PSD.
thanks!
3/15==
1/5
Know bit late to the oarty vut havnt factored since hs i am now 24 and in pre cal... yea little bit a culture shock but small bit are slowly coming back. Thank you
this video saved me from failing math thanks so much❤
There is a simper way. a*c= 5*9 = 45, and b=a+c= -18 => a and c = -3, -15 => apply ax and use -3 and -5 => (ax -3)*(ax-15)=> (5x-3)*(5x-15) => simplify by removing common factors =>(5x-3)*5(x-3) => remove common factor 5 => (5x-3)*(x-3)
Thank you.
sir thank you so much 🙂
Oh my god randy Orton is teaching now teaching math😱😱😱😱😱😱
hi brian! i’m doing some college algebra and they’re showing me a problem with a 1 in the middle for example your problem 5x2 - x + 9 that always messes me up what can i do
This helps a lot especially since I’m taking a test 😭 thank you 🙏
Bruh the jidion pfp 💀

what grade were you teaching here
Bro i fucking love you
Here I am doing math...as if I need it in the future-...I wanted to be an artist not a mathematician :')
why not be a NASA engineer
Brian is here for me when photomath isn't.
Haha yes
how would you multiply a*c when a is a letter^2?
Say again?
@@brianmclogan Oh, i was wondering how you would multiply a times c is a is squared
Was this a trinomial or quadratic
a quadratic with three terms is also know as a trinomial, quadratic classifies the degree of a polynomial where trinomial classifies how many terms, different ways to classify the same polynomial
who has a test tomorow??
I got it next hour😭

Nice work! I have a gripe with the teaching system. Would you see someone with a bachelors, masters, or phd using this method (or any of the other ridiculous methods) to solve a quadratic? NO. If not, then why are we teaching it. Another mindless game to confuse the masses. Learn and use the quadratic formula which works for everything. Quit confusing students with all the methods of idiots. Again, this is a gripe of the teaching system. THIS HAS NOTHING TO DO WITH THE GREAT JOB BRIAN IS DOING.
Look- its not that hard kids. You dont need these 40 steps.
Look at the last number in the equation- 9
You know that you need two numbers that multiply to make 9. I know- it's super difficult.
Look at the number next to x2- 5; you know you need 2 numbers that multiply to 5.
That one is very difficult.
So at this point, you understand u are working with 1/5, and either 3/3 or 1/9
Super hard to just throw those numbers in and multiply it out to find the answer. Its what we did 25 years ago when I went through HS Trig, before common core came along and made everyone dumber. Sorry kids.
