FactorTerms

FactorTerms[poly]

pulls out any overall numerical factor in poly.

FactorTerms[poly,x]

pulls out any overall factor in poly that does not depend on x.

FactorTerms[poly,{x1,x2,}]

pulls out any overall factor in poly that does not depend on any of the xi.

Details and Options

  • FactorTerms[poly,x] extracts the content of poly with respect to x.
  • FactorTerms automatically threads over lists in poly, as well as equations, inequalities and logic functions.
