Try this:
\n" ); document.write( "\"A+=+L%2AW\" Substitute A = 216, and L = W+6
\n" ); document.write( "\"216+=+%28W%2B6%29%28W%29\"
\n" ); document.write( "\"216+=+W%5E2%2B6W\" Rearrange to:
\n" ); document.write( "\"W%5E2%2B6W-216+=+0\" Factor.
\n" ); document.write( "\"%28W%2B18%29%28W-12%29+=+0\" so...
\n" ); document.write( "\"W+=+-18\" or \"W+=+12\" Discard the negative solution.
\n" ); document.write( "\"W+=12\" and...
\n" ); document.write( "\"L+=+%28W%2B6%29\"
\n" ); document.write( "\"L+=+18\" so...
\n" ); document.write( "The length of the cutting board is 18 inches and the width is 12 inches.
\n" ); document.write( "
\n" );
