Collect

Collect
collects together terms involving the same powers of objects matching x.
Collect
collects together terms that involve the same powers of objects matching , , ....
Collect
applies h to the expression that forms the coefficient of each term obtained.
  • Collect effectively writes expr as a polynomial in x or a fractional power of x.
  • Collect[expr, x, Simplify] can be used to simplify each coefficient separately.
  • Collect automatically threads over lists in expr, as well as equations, inequalities and logic functions.
