Question about Casio FX9750GII Graphic Calculator

Ad

What is the question. Your calculator FX-9750 GII does not have a Computer Algebra System or CAS, so you cannot factor a polynomial.

If you want you can try to find the zeros of the polynomial function (the values of x when the function crosses the horizontal axis) either by solving P(x)=0 or by graphing y=P(x).

Once you have the approximate roots x_1, x_2, ...,x_n, you can factor out the coefficient of the leading term (the term with the highest power) and write P(x) =a_n *G(x). here a_n is the coefficient of the leading term.

G(x) can then be written as G(x)=(x-x_1)(x-x_2)*(x=x_3)...(x-x_n)

and the original polynomial will be

P(x)=a_n(x-x_1)(x-x_2)*...*(x-x_n)

Note: Here is an example of P(x) and the corresponding G(x)

P(x)=5x^3+7x^2-13x^+29

P(x)=5**(x^3+ (7/3)*x^2-(13/5)x+29/5)**

G(x)=**x^3+ (7/3)*x^2-(13/5)x+29/5**

You should keep in mind that the roots are in general complex. Not all polynomials are factorisable in the set of Real numbers.

There is a program on page 253 of the manual (http://support.casio.com/manualfile.php?rgn=5&cid=004002013) to get the prime factors of any number. You could modify the program to get all the factors.

Another way would be to do it manually. I start with the number 1 and go up to the square root of the number. The square root of 120 is 10.95, so let's go up to 11. Using 120 as an example:

120 /1 = 120 thus factor is (1, 120)

120/2 = 60 thus factor is (2, 60)

120/3 = 40 thus factor is (3, 40)

120/4 = 30 thus factor is (4, 30)

120/5 = 24 thus factor is (5, 24)

120/6 = 20 thus factor is (6, 20)

120/7 = 1.7 thus 7 not a factor

120/8 = 15 thus factor is (8,15)

120/9 = 13.3 thus 9 is not a factor

120/10 = 12 thus factor is (10,12)

120/11 = 10.9 thus 11 is not a factor.

Good luck.

I just had this problem. I had factor A as ***, factor B as age, and I was trying to look at my RM data. What I needed to do was separate it out, so that I was looking at factor A as ***, factor B as "session"- my repeated measure. Then I did a separate analysis with factor A as age, factor B as session.

Natively, the calculator cannot factor polynomials because it does not have a Computer Algebra System or (CAS). You can however find the roots of the polynomial equation P(x)=0 and factor approximately.

On the Internet, there is a program which you can download and transfer to your calculator. Here is the link (the page is in French).

Here is a link to Ticalc.org
where you can find programs that do prime factorization. You should
read the description of each program to find out if it answers your
questions.

Hi,

There 4 or 5 programs for the TI83/4Plus family of calculators available at ticlac.org. Scroll down the page to find them. Download them and transfert to your calculator using TIConnectivity software.

Hope it helps.

Thank you for using fixYa and for rating the solution.

Well, to answer part of your question, yes... the TI-89 does factor like this. it is inputted like this:

factor(6*x^2+11*x+4,x)

Check the catalog in the TI-84 (which is 2nd-zero) and look under F for factor()

factor(6*x^2+11*x+4,x)

Check the catalog in the TI-84 (which is 2nd-zero) and look under F for factor()

x^2+5x+7 won't factor any more.. if you're trying to solve it, do:

solve(x^2+5x+7=0,x)

solve(x^2+5x+7=0,x)
