Hi Mary: lets rewrite this and maybe you'll get an idea of how to do this next time you see it $\"25x%5E2+-+36\"$ ......rewrite to:
\n" ); document.write( ":
\n" ); document.write( " $\"%285x%29%5E2-6%5E2\"$ if you look closely you should see something familiar
\n" ); document.write( ":
\n" ); document.write( " $\"a%5E2-b%5E2\"$ difference of squares just plug in the numbers for that formula
\n" ); document.write( ":
\n" ); document.write( "using 5x for a and 6 for b.
\n" ); document.write( ":
\n" ); document.write( " $\"%285x-6%29%285x%2B6%29\"$ \n" ); document.write( "

\n" );
