I have a very long equation that I need to break up. I can't seem to get
LaTex to break a line in math mode. Clearly this is possible but every attempt
so far has failed. The equation reads:

\begin{displaymath}
\left(
{-{2 \  {b \sp 2} \  {x \sp 2} \  {\sqrt {3}} \  {\log 
\left(
{{{{\root {3} \of {a}} \  {{\root {3} \of {{{b \  x}+a}}} \sp 2}}+{{{\root 
{3} \of {a}} \sp 2} \  {\root {3} \of {{{b \  x}+a}}}}+a}} 
\right)}}+
{4 \  {b \sp 2} \  {x \sp 2} \  {\sqrt {3}} \  {\log 
\left(
{{{{{\root {3} \of {a}} \sp 2} \  {\root {3} \of {{{b \  x}+a}}}} -a}} 
\right)}}+{{12}
\  {b \sp 2} \  {x \sp 2} \  {\arctan 
\left(
{{{{2 \  {\sqrt {3}} \  {{\root {3} \of {a}} \sp 2} \  {\root {3} \of {{{b \  
x}+a}}}}+{a \  {\sqrt {3}}}} \over {3 \  a}}} 
\right)}}+{{\left(
{{12} \  b \  x} -{9 \  a} 
\right)}
\  {\sqrt {3}} \  {\root {3} \of {a}} \  {{\root {3} \of {{{b \  x}+a}}} \sp 
2}}}
\right)
\over {{18} \  {a \sp 2} \  {x \sp 2} \  {\sqrt {3}} \  {\root {3} \of 
{a}}} 
\end{displaymath}

Suggestions are welcome.
