Transform your expression into the particular form you require
(expanded, factored, or expressed in particular terms) by choosing
the appropriate function. See Choose Function to Rearrange Expression. If you just
need a simpler expression, use
You also can substitute for any part of an expression with another
value by using
|Simplify Symbolic Expression||Simplify symbolic expressions in Live Editor|
|Coefficients of polynomial|

|Horner nested polynomial representation|
|Extract numerator and denominator|
|Partial fraction decomposition|
|Subexpressions or terms of symbolic expression|
|Combine terms of identical algebraic structure|
