Apart[] doesn't work with repeated factors in the denominator #9

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Input: 
  Apart[(10*x^2-63*x+29)/(x^3-11*x^2+40*x-48)]

The third case: "A repeated first-degree factor in the denominator"
in the Wikipedia Example:
 http://en.wikipedia.org/wiki/Partial_fraction
doesn't work

Output from JAS:
Exception in thread "main" java.lang.RuntimeException: not solvable, r
= -63 , c = 10 x^2 - 63 x + 29 , g = x - 4
