Here is the original problem:
\n" ); document.write( "(i) $\"4a%5E2%2B12ab%2B9b%5E2-25c%5E2\"$
\n" ); document.write( "look carefully, we really have this
\n" ); document.write( "(ii) $\"4a%5E2%2B12ab%2B9b%5E2\"$ - $\"25c%5E2\"$
\n" ); document.write( "which is the difference of two squares.
\n" ); document.write( "Factoring (ii), we get
\n" ); document.write( " $\"%282a%2B3b%29%5E2\"$ - $\"%285c%29%5E2\"$
\n" ); document.write( "factoring as a difference of two squares, we get
\n" ); document.write( " $\"%282a%2B3b-5c%29%282a%2B3b%2B5c%29\"$ \n" ); document.write( "

\n" );
