Algebraic manipulation
Hi,
How can I manipulate a algebraic expression trying to extract a used defined term. Exemple: (4x12) > I know I can factor this term. Does exists any kind of control that I can specify a term? I would like to specif "(x3)" > 4.(x3) Another Exemple: (3(4/5x)(5) > I would like to specify a term "(x10)" and see it´s possible. Does the calculator can do that? Or any alternative? Thanks

RE: Algebraic manipulation
I don't know of a way to use a specific factor.

RE: Algebraic manipulation
I think "factor()" and "simplify" will do the trick
Oh … and make sure you're in the CAS "ambient" ! Best, Aries

RE: Algebraic manipulation
Usually , I ´ve been using the factor and simplify command as mentioned. But I would like to specify a factor if possible...
Thanks Best, Mario

RE: Algebraic manipulation
Bruce,
I like your strategy the best  use the simplify(p(x)/q(x)). The CAS program specfactor uses this strategy to factor q(x) from p(x): Code:
Successful factoring returns the result as strings (to preserve the format without automatic simplification): specfactor(4x12,x3) returns "(4)*(x3)" [ 4(x3) ] specfactor(84/5*x,x10) returns "(0.8)*(x10)" specfactor(x^3 x^2+2*x2,x^2+2) returns "(x1)*(x^2+2)" Eddie
