I have looked all over for a program that will factor
things like
x^4+3x^3+2X+5 into (?+?)(?+?)
Any help?

That would revolutionise my mathematic skills.
I hope it can be done, I've got a feeling the calculator has to use brute force. Which is not very satisfying.

Try looking at this link from Charlie Watson's website: http://www.charliewa...fx/prog_cfx.cat
It contains programs for multiplying polynomials (which is what you want I guess....), dividing, etc.....

nope, factorizing is to fully decompose a polynomial in it's basic factors.It contains programs for multiplying polynomials (which is what you want I guess....), dividing, etc.....
you have a CFX calc js737. then, surely you can solve poyinomials at least grade 3 (?). so you need to program any numerical method for polynomial root finding (ie Bairstow method). A sweet solution is graphing the poly and finding the zeros via the solve function built in the graph mode. then build the factorization by hand

I wonder if this can help you though, it can factorize only quadratics (power 2): http://www.charliewa...io/casprog.html
Look for QUADSOLV

It's easy for degrees 3 and 2, possible for degree 4 if you know one root, beyond, it's getting tough.
for degrees 3 and 2, and degree 4 (if you know one root), you don't really need a program.
The factors are (x-root 1)(x-root 2) etc.

The soluion of equation of any degree from -4 to 4 can solve by hand a little easily, the higher degree cant solve in some cases.

Eqn4: Factor to 2 equation degree2, that's simple.
Eqn3: Canado and some else.
