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.

G(x)=x^3+ (7/3)*x^2-(13/5)x+29/5 should read G(x)=x^3+ (7/15)*x^2-(13/5)x+29/5

### How do I get all the factors of a constant using my calculator?

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.

### SigmaStat two-way repeated measurement ANOVA: error message: You have more than one measurement for a subject within a cell! I checked everything and the data are organized as usual (one subject column,...

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.

### I don't have a mechanical problem with the calculator, but I have a question. Will my Casio factor quadratic trinomials?

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).

### Can you Factor on a TI-84? IF not, does the TI-89?

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()

### Factoring

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

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