No it does not. Sorry. I checked their website and they do not have programs that could factor an arbitrary polynomial.

Can casio fx-991es factor?


No it cannot factor. It does not do symbolic manipulations.If you know a bit of theory of polynomials you can find the roots of the polynomial equation. The calculator has a Solve utility. Once you have the roots, you can use your knowledge about polynomials to carry out the factorization procedure.

How to calculate the standard deviation? casio power graphic fx-7400G Plus


Here are the capabilities of the Casio calculators.
The screen captures may not look like ones taken from the FX-7400G
plus display but the instructions are accurate.
In stat enter the values in List1 and the frequencies in List2 (if doing paired variable statistics)
Press the key corresponding to the CALC tab

Press the 1-var tab and you get the results as seen on the screen with title 1-variable.
Other screens show some two-variable stats or regressions.

I cant find the factorial function on my casio FX-7400G Plus calculator


To find the factorial command, go to the Run screen and press [OPTN] [F4] (PROB) [F1] (x!). For example, to find 5!, press 5 [OPTN] [F4] [F1] [EXE].

Can I factor a polynomial with a Casio fx-9750GII calculator


The short story is that this calculator does have a computer algebra system or CAS and thus cannot factor polynomials with arbitrary (unknown) coefficients or known coefficients.
However if the coefficients are given you can ,if you are willing to travel that way, factor approximately a polynomial P(x).
Basically, the idea is that any polynomial P(X) of degree n can be written in the factored form (X-x_1)(X-x_2)...(X-x_n), where x_1, x_2, x_3,...x_n are the roots (real or complex) of the equation P(X)=0.


The procedure ( for a 3rd degree polynomial) is as follows: (the fixYa site parser will remove the plus signs, so I am writing the whole word plus instead of the mathematical sign
If you want to factor a cubic polynomial P3(X) = aX^3 plus bX^2 plus cX plus d , you write the corresponding cubic equation as aX^3 plus bX^2 plus cX plus d =0 , then you divide all terms of the equation by a to obtain

X^3 plus (b/a)X^2 plus (c/a)X plus (d/a)=0.

You use the calculator to solve (approximately) this equation.
Suppose you find the 3 roots X1,X2,and X3. Then the polynomial X^3 plus (b/a)X^2 plus (c/a)X plus (d/a) can be cast in the factored form (X-X1)(X-X2)(X-X3) and the original polynomial P3(X) can be written as

P3(X) = a*(X-X1)(X-X2)(X-X3)

You can handle the quadratic polynomial the same way.
P2(X) =a*(X-X1)(X-X2) where X1, X2 are the two real roots.

To find the various roots you must use the solve( application.

Can i solve an equation of second degree(like X^2+2X+1) with Casio FX-7400G Plus ? If so how?


Sorry but the calculator does not have a solving routine. You can however use the graphing capabilities of the Casio FX-7400GPLUS to solve an equation f(X)=0.
  1. Graph the function Y=f(X)
  2. Use the trace function to locate the point(s) where the function vanishes (has value Zero)
See the screen capture for an example.

If you were hoping that this calculator would be able to factorize polynomials for your, sorry my friend it cannot.

How to factor a polynomial equation on casio fx-300es?


Hello,
The Casio FX-300ES does not handle symbolic algebra. So it cannot factor a general polynomial expression. The methods can be found in any book on Algebra.
However if you are interested in approximate factorization of quadratic and cubic polynomials, you can use the calculator to do that. It can solve aX^3 +bX^2+cX+d =0 and the quadratic equations.

If you want to factor a cubic polynomial P3(X) = aX^3+bX^2+cX+d , you write the corresponding cubic equation as aX^3+bX^2+cX=d =0 , then you divide all terms of the equation by a to obtain

X^3+(b/a)X^2+(c/a)X+(d/a)=0.

You use the calculator to solve (approximately) this equation.
Suppose you find the 3 roots X1,X2,and X3. Then the polynomial X^3+(b/a)X^2+(c/a)X+(d/a) can be cast in the factored form (X-X1)(X-X2)(X-X3) and the original polynomial P3(X) can be written as

P3(X) = a*(X-X1)(X-X2)(X-X3)

You can handle the quadratic polynomial the same way.

P2(X) =a*(X-X1)(X-X2) where X1, X2 are the two real roots

Hope it helps.
