Is there any way to simplify (-12*x - 1)*(2*x3 + 3*x2 - 2*x - 5) + (-6*x2 - x -
7)*(6*x2 + 6*x - 2) ？ I want to get the final result ,not an intermediate one.

can Convert the given expression to LaTeX representation,but is there any

i.e. is there any function can take

Consider the following short example:

What's "composable" in this context?
Easy to write without intruding too much into the actual function.
OK
That would not affect SymPy itself, as it is not multithreaded.
No, but it would affect anything that tried to run sympy functions th

Go ahead and open a pull request with this change, and we can review
it, and see if it breaks any tests, and so on.

We don't have it but we do want it. See
https://github.com/sympy/sympy/issues/5418. Note that parse_expr can
already handle the basic stuff (like implicit multiplication).

I would like to work upon this issue which has been reported.
https://github.com/sympy/sympy/issues/7570
Would someone please tell me, how to get started with this?
Where should I start to look for this issue?
Highly eager to get this going. Sorry, to be asking so trivial questions.

The first approach was hackish (actually both are, but the decorator way is
*significantly* better). And I agree, I'm still not sure this a problem
worth solving. Just food for conversation. I posted some timings on the
decorator PR https://github.com/sympy/sympy/pull/8297
The core tests ran ab
I have thought a bit more, and it *would* open up using SymPy inside
other applications (GUIs, as part of an array of problem solvers,
whatever). Can't name any concrete killer app, but making a piece of
software more generally useful and seeing what people make of it is
always a good idea.
