When I try to factor a polynomial on my calculator it gives the answer as the same problem I put in. For example, if I say factor(3x^2+6x+9) it says the answer is 3x^2+6x+9. When I first got the calculator a few months ago it worked fine, but now it does this for almost any application I try to use.

The polynomial cannot be factored in the set of Real numbers: The roots of the polynomial equation are complex.

You should use the command **cFactor(** found under F2:Algebra> A:Complex>2:cFactor(

However, you should set the Mode Complex>Rectangular, and the EXACT/APPROXIMATE mode to Exact, otherwise your roots will be in decimal representation.

SOURCE: 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()

This simple scientific calculator does not factor polynomials. Get a calculator with a Computer Algebra System.

No, your calculator cannot factor polynomials. You need a calculator that has a CAS (computer Algebra System)

Yes Casio sells calculators with CAS: The FX-Algebra 2.0 and 1.0, the FX-9860GPLUS/GII SD, the GRAPH85 or 80 and the Graph 100+. You also have the CLASSPAD Series 300PLUS and 330.

TI and HP also have CAS calculators.

Hewlet-Packard

HP 48G/G+/GX, HP40G, HP49G/G+ and the top of the line HP50G

You apparently have a numerical value stored in the variable "x" and the calculator is using that value. To get rid of it, press 2ND [VAR-LINK], scroll down to the line containing the variable x, press F1 1.

The calculator does not give a result of an integration with a constant. The form of the result will depend ob the EXACT/APPROXIMATE mode you have selected.

In the following screen capture, your integral has been evaluated with mode set to EXACT,AUTO, and APPROXIMATE. Pay attention to the syntax.

To set the computational mode to EXACT, press the MODE button use the Function keys F1,F2 or F3 to move from page to page, point to EXACT/APPROX and use the right arrow key to unfold the submenu, then the Up or Down arrow to select AUTO, EXACT or APPROXIMATE and press ENTER to SAVE Configuration.

If the integral cannot be found in EXACT mode, the calculator will echo the command without calculating the integral.

the 89 is in my opinion not need/ approriate for a 10th grade algebra class, or worth the extra money.

for example the 84 wont output variables it must output a number

so your son may be doing factoring, if he inserts (x^2+2x+1) the 89 will allow him to enter it and factor it as (x+1)(x+1) or (x+1)^2 the 84 will not.

the 84 will do pleanty as far as graphing, finding zeros,plotting, calculations, and should get him any answer that he seeks so long that he knows how to use the 84. It just wont give him the intermediate steps the the 89 is able to give.

hope this helps

oh yeah, you must've archived x, that is, you put a number onto the x variable so that the calculator calculates the answer for you, and THEN AUTOMATICALLY calculates the answer when x is in terms of that number. I am guessing you accidentally did 10[sto] x at one point. You can simply unarchived the x number and everything will be dandy!
