### Describe the algorithm/code
This is a method in mathematics that is used to find the roots of a polynomial equation.
I want to add an implementation of this method in python.

mat.jordan_form(CDF) gives the wrong Jordan form for some matrices because mat.charpoly().roots() sometimes gives separate roots when it should give a single root. Attached is a patch that adds a ne…

I wonder what role does variable 'qn' play?
```python
qn = 8 # original value
qn = 50
print(' Quadrature order = %d' % (qn))
```
If I change 'nu':
```python
vtn = 1…

The 3 (real) roots of the polynomial `x^3 - 3x + 1` sum up to `0`. Currently there does not seem to be a function in sympy that is able to simplify the sum directly:
```python
>>> from sympy import …

Currently the modulus of the polynomial factorization calculator must be a prime number or a power of a prime, but I think that a general composite number modulus should be possible, e.g. for a polyno…

The `rootof` function fails to find the roots of `x**4 + 4*x**1 + 1` and returns a `CRootOf` instead. It works for other quartics but not this one:
```julia

Greetings,
I am running sympy (0.7.6.1) in Python 3. When I ask sympy to solve for the roots of a single-variable cubic polynomial with complex coefficients, sympy crashes with a rather strange er…
