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.
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.
From left to right the icons across the top: M memory register in use, Textbook-entry (MathI) mode enabled, Degrees (vs Radians -- this is the square I think you are referring to), and calculator powered by solar panel only (far right).
@@scottcollins7513 Thanks for your reply, i mean this thing on the top right of the calculator itself (not in the screen) which looks like small screen
@@scottcollins7513 Haha this little misunderstanding actually ended up finally teaching me what those symbols on the top meant! Thanks for the concise info and quality video sir!!
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.
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).
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.
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.
I have equation ysquare-62y+336 my calculator is giving answer in points but the answer is( y-6)(y-56) my ca Calculator is giving 67.1 and 5.1 please help me get correct whole answer from my calculator i have casio fx991ex classwizz
@@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.
