how do i express the factors of a polynomial in a list

so want something that does

giving output

Ah. So you need to make that assignment (outside of the function):
ef=polyran()
quickfactor(ef)
or even shorter:
quickfactor(polyran())
Note that the ef defined inside of polyran is local to that function; it
is not v
ef is the resultant of poly_ran

suppose i have a funciton
def_f1(f)
f=2
return f
how do i then make the output f the input of a antother function
def_eg1(f)
g=f^2
return g
as at the moment its telling me that f isnt defined
Can you include a complete code
