I reset the calculator and it did its job- though a solution would be handy.

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()

yes get some dust off from the store this will clean it. you can even go as far as putting a little tiny drops of baby oil into the cracks thats what i would do

SOURCE: how to change a fraction into a decimal

This is a partial solution for I do not have the TI89 titanium with me.

1. The easiest way is to insert the decimal mark (. dot or , comma) at the end of one of the elements of the fraction (numerator or denominator).

Ex: if you enter 1/2 the calculator displays the fraction 1/2, but if you enter 1./2 or 1/2. or 1./2. it displays 0.5

2. You can also configure the EXACT/APPROXIMATE mode option of the calculator ( Press Mode then scroll till you see exact/approximate) then choose AUTO, EXACT, or APPROXIMATE.

In the EXACT option the calculator will perform exact algebra ( Pi remains Pi not 3.14159... ).

In the APPROXIMATE option, calculations are performed numerically (everything is treated as a decimal number.)

In the AUTO option the calculator will try its best to keep the results as exact as possible :

x/6 + 1/2 yields x/6 + 1/2

x/6. + 1/2 becomes .166666..x +1/2

x/6. + 1./2 becomes .16666..x +0.5

My suggestion ( if you allow me) : Leave the calculator set on AUTO, and convert to decimals as needed by putting the decimal mark at the end of an integer.

I hope it helps.

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

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.

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.

Texas Instruments

TI 89 /Titanium, Voyage 200PLT, TI92PLUS (discontinued), TI Inspire CAS.

Hewlet-Packard

Having gone over a month with no response, I assume this is no longer a problem.

If you connect calculator to computer using Ti connect device explorer you might be able to see what files are on the calculator. I don't know if you downloaded from the web but, 3rd party programs and shells tent to miss up the calculator. This would able you to delete out possible problems which could be re installed later.
