Here are two ways:
\n" ); document.write( "1)
\n" ); document.write( "x^2=16
\n" ); document.write( "x=+-4
\n" ); document.write( "x=-4
\n" ); document.write( "x=4
\n" ); document.write( "x^2=16
\n" ); document.write( "2)
\n" ); document.write( "factor
\n" ); document.write( "(x+4)*(x-4)=0
\n" ); document.write( "x+4=0
\n" ); document.write( "x=-4
\n" ); document.write( "x-4=0
\n" ); document.write( "x=4
\n" ); document.write( " \n" ); document.write( "
\n" );
