FactorList
Usage Message: FactorList[poly] gives a list of the factors of a polynomial, together with their exponents.
Attributes[FactorList] = {Protected} Options: Extension
-> None

Notes: FactorList is similar to Factor
except that factors are returned as a list rather than in a product. The result from Factor
can be constructed by combining the factors and exponents returned by FactorList. For example:
In[1]:= expr = FactorList[28 x^2-7 y^2]
Out[1]= {{7, 1}, {2 x - y, 1}, {2 x + y, 1}}
In[2]:= Times @@ Apply[#1^#2 &, expr, {1}]
Out[2]= 7 (2 x - y) (2 x + y)
In[3]:= Factor[28 x^2-7 y^2]
Out[3]= 7 (2 x - y) (2 x + y)
