\n" ); document.write( "20q to the second power minus 5r to the second power
\n" ); document.write( "20q^2-5r^2
\n" ); document.write( "factor out 5
\n" ); document.write( "5*(4q^2-r^2)
\n" ); document.write( "difference of squares
\n" ); document.write( "5*(2q-r)*(2q+r)
\n" ); document.write( "
\n" );
