I've just started using SMath Studio btw, so apologies if these questions are a bit basic. I have been searching around for answers but couldn't find anything hence I'm posting questions to the forum.
How do I factorize the following expression?
6.p^3 - 30.p^2 + 40.p - 20
I'm using the Windows edition of SMath Studio, build 0.89 (build: 3856)

Hello bluesky
I think that SMath has no such a feture yet. For example: 6*p^3-3*p^2-2*p+1 Symbolic engine will give you something like this: 6*p^3-3*p^2-2*p+1—1+p*(-2+p*(-3+6*p)) At least you can do having a polynomial is to find roots with polyroots (numerical values): a←polyroots(mat(1,-2,-3,6,4,1)) a=mat(-0.58,0.5,0.58,3,1) p←5 6*(p-el(a,1))*(p-el(a,2))*(p-el(a,3))=666 6*p^3-3*p^2-2*p+1=666@#
