#12964: Boost polynomial multiplication
 Reporter: Adam Biggs <ambiggs23@…> | Owner: johnmaddock
     Type: Bugs | Status: new
Milestone: To Be Determined | Component: math
  Version: Boost 1.63.0 | Severity: Problem
 Keywords: polynomial |
 Very simple little issue. After multiplying two
 boost::math::tools::polynomial s
 together the function polynomial::normalize() is not called and thus we
 don't reduce polynomials to their natural form. Note that it is called for
 the more general multiplication e.g

 polynomial<int> p{0};
 polynomial<int> q{1, 1};

 std::cout << (p * q == p) << (0 * q == p)


 Simple fix is to jsut call normalize() after the polynomial multiplication
