KhiCAS, le moteur formel Giac/Xcas pour toutes TI-Nspire

Yes it does factor for example

$mathjax$2x^2-3x+1$mathjax$

.
But, in general, it won't factor formal expressions.

What did you ask exactly to KhiCAS ?

[r4nd0mdvr]

how do you factor that?

[Hamza.S]

with khiCAS, factor(expr) for example factor(2*x^2-3*x-1)

[r4nd0mdvr]

do you have a download link?

i might have an outdated version. when i factor that quadratic, it returns as undef(2)-3x-1

however, when i factor a quadratic with a leading coefficient of 1, it works out

[Hamza.S]

you must use after 2

[r4nd0mdvr]

what's that? Sorry for my lack of understanding btw maybe an example or screenshot would help...

[Adriweb]

Use multiplications explicitely

[r4nd0mdvr]

example? when i enter that in, it replies undef(2)-3x-1

[Adriweb]

3*x and not 3x.

I don't know if that is the problem, but it can only be better when things are done well in the first place.
