Better late than never! Glad it was helpful to you, Satyam. Factoring gives a lot of people trouble -- it's really tough if you are someone who struggles with knowing all the divisors of a given number. The good news is that you'll probably never need to factor anything in the "real world".
Glad to hear I could help. You have a great calculator! Obviously, if you can also learn how to factor without it, that would be ideal. All the best to you. Thanks for leaving a comment!

I think you are talking about “FOIL”ing (e.g. expanding (x+2)(x-3) ). If so, the news is not good. You would need a calculator with CAS (computer algebra system) to do so.
It is the difference between ROOTS (aka "Zeros") and FACTORS. The calculator is telling you what x values when plugged back into the equation will give you a y value of ZERO. To get the factors you need to reverse the sign. When calculator gives us the ROOT x=2, we can then use that to determine that the corresponding factor will be (x-2).
Yes. If the roots that the Casio gives are x1=-3 and x2=-7, then your corresponding factors will be (x+3) and (x+7) -- you simply flip the signs, exactly as you are suspecting.
Could you give me an example? Are you thinking something like 3x-18? Regardless, I do not have any particular tricks for factoring linear expressions with this calculator -- UNLESS your particular version of the fx-991EX happens to have the "GCD" (greatest common divisor) function.
It looks like you have a nice calculator, but it looks like it does not have the more-advanced features of the fx-991EX. You are probably going to need to learn to do this the "old fashioned way" (how your teacher shows you). The calculator in the video is using the "quadratic formula" to find the two roots it gives, but using that formula is probably going to be much tougher than following the steps that your teacher provides. Sorry I do not have any better suggestions.
A calculator with a "Computer Algebraic System" (CAS). A few are: HP Prime, TI Nspire CX CAS, TI-89. They are rarely allowed in math classes for this reason.

@@scottcollins7513 I am at the university of France it is for my state exam I need the function 1 cdf I would like to know if it is a programmable calculator or not because the programmable calculator is prohibited?
@@roseytb4092 You should double-check with the French website for the exam, but I will say that the fx-991EX Classwiz is NOT a programmable calculator and therefor is typically allowed for these types of exams. Just make sure you are very comfortable with whatever calculator you end up getting -- practice with it! Best wishes on your exam.
spent 2 semesters in college and now i get to know how to do this...This is so helpful. Thank you

Me after 5th sem
My MATHS teacher said that using this calculator for finding quadric factors is so hard, you should change your calculator.
Thank God I found you.

Thank you so much, I didn't even know this was possible, now i can be sure of my answers in exams haha
Always happy to hear that a video has been helpful -- thanks for taking the time to let me know.
Thank you Mr.Collins
Very Helpful... Just letting you know this works in any casio fx- model!
Thanks for leaving a note. Good point about it working with other fx models.
this is so helpful. thank you so much !!
Always happy to know when it has helped someone out -- appreciate you taking a little time to let me know! Take care.
Thank you very much
Your a blessing thank you ❤🙏
Appreciate your kind words! Glad it was helpful to you.

Holy F dude !
What's the name of that cool writing pad thingy? Thx!
It's called a reMarkable. Mine is a version 1. They are on version 2.

Is the fx-5800P programmable calculator available in USA?
I don't think it is. I think we would have to order from Europe/Asia.
amazon
No, it’s an Atlantis exclusive
Thnx, can you tell me what is this small square in the top of the screen?

@@scottcollins7513 thank you
@@scottcollins7513 Hi, can you please let me know the which type is CAS?
@@la10sooony CAS stands for Computer Algebraic System. Calculators like HP Prime, TI Nspire CX II CAS , Casio fx-CP400 are CAS calculators.
There should be a reason, why x=2 turns out to be x=-2 for the calculator to do it correctly?
It is the difference between ROOTS (aka "Zeros") and FACTORS. The calculator is telling you what x values when plugged back into the equation will give you a y value of ZERO. To get the factors you need to reverse the sign. When calculator gives us the ROOT x=2, we can then use that to determine that the corresponding factor will be (x-2).
i dont understand how u changed the positives into negatives and vice versa, is that how it works?
Yes. If the roots that the Casio gives are x1=-3 and x2=-7, then your corresponding factors will be (x+3) and (x+7) -- you simply flip the signs, exactly as you are suspecting.
How to you factorise a linear expression with the calculator
Could you give me an example? Are you thinking something like 3x-18? Regardless, I do not have any particular tricks for factoring linear expressions with this calculator -- UNLESS your particular version of the fx-991EX happens to have the "GCD" (greatest common divisor) function.
@@scottcollins7513 mine has the Gcd function how would I use it
@@rohanprabhudesai9394
Let's assume you wanted to factor 6x-15.
Step 1 - GCD(6,15) = 3 (this is greatest common factor)
Step 2 - Divide 6 by 3 = 2
Step 3 - Divide -15 by 3 = -5
Step 4 - Rewrite as: 3(2x-5)

Check for typos and make sure you use the NEGATIVE key when you enter the -62 just to be safe.

What exams are we talking about? ACT = yes. Spanish Class = doubtful.
