So, set up our problem:
\n" ); document.write( " $\"7a%5E2b%5E2-ab-2ab%5E2-%28-5ab%5E2%2B3a%5E2b%5E2-a%5E2b%29\"$
\n" ); document.write( "We need to distribute the - sign to every term in the second part so:
\n" ); document.write( " $\"7a%5E2b%5E2-ab-2ab%5E2%2B5ab%5E2-3a%5E2b%5E2%2Ba%5E2b%29\"$
\n" ); document.write( "Then we can combine any like terms:
\n" ); document.write( " $\"7a%5E2b%5E2-3a%5E2b%5E2=4a%5E2b%5E2\"$
\n" ); document.write( " $\"-2ab%5E2%2B5ab%5E2=3ab%5E2\"$
\n" ); document.write( "both the $\"-ab\"$ and tje $\"a%5E2b\"$ have no like terms to be combined with, so they are left alone.
\n" ); document.write( "These answers all yield the final equation of:
\n" ); document.write( " $\"4a%5E2b%5E2%2B3ab%5E2-ab%2Ba%5E2b\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
