Simplify

Simplify[expr] performs a sequence of algebraic transformations on expr and returns the simplest form it finds.

Simplify tries expanding, factoring, and doing other transformations on expressions, keeping track of the simplest form obtained.

Simplify can be used on formulas, equations, and inequalities.

Objects that are specified as satisfying inequalities are always assumed to be real.

You can paste a template for this command via the Text Input button on the Simplify Function Controller.

Simplify returns these polynomials in factored form.

In[2]:=

Out[2]=

In[3]:=

Out[3]=

This variation shows that Simplify may not factor completely.

In[4]:=

Out[5]=

And here Simplify does nothing at all.

In[6]:=

Out[6]=

This integral returns a sum of three terms. This uses ordinary mathematical notation for Integrate.

In[7]:=

Out[7]=

Differentiating the result gives an expression that is more complicated than the original integrand, but mathematically equivalent to it. This uses ordinary mathematical notation for D.

In[8]:=

Out[8]=

Simplify gets back to the original form of the expression.

In[9]:=

Out[9]=
