Factor:
\n" ); document.write( " $\"4w%5E2-u%5E2\"$ This is a difference of two squares: $\"%282w%29%5E2-%28u%29%5E2\"$ and it is factorable like this:
\n" ); document.write( " $\"A%5E2-B%5E2+=+%28A%2BB%29%28A-B%29\"$ so, for your problem:
\n" ); document.write( " $\"4w%5E2-u%5E2+-+%282w%2Bu%29%282w-u%29\"$ \n" ); document.write( "

\n" );
