Well, we start by pulling out a 2...
\n" ); document.write( "2z^2 - 196c^2 =
\n" ); document.write( "2(z^2 - 98c^2)
\n" ); document.write( "Now this is the difference of squares, except that 98 is not a perfect square, but we can still use the proper form, like this
\n" ); document.write( "2(z^2 - 98c^2) =
\n" ); document.write( "2(z + 7c*sqrt(2))(x - 7c*sqrt(2)) \n" ); document.write( "

\n" );
