\n" );
document.write( " x^2 - 8x-16y+16 =0
\n" );
document.write( " x^2 - 8x = 16y-16 
\n" );
document.write( "(x-4)^2 = 16y - 16 + 16
\n" );
document.write( " (x-4)^2 = 16y
\n" );
document.write( "  y = (1/16)(x-4)^2  V(4,0)  x = 4 line of symmetry
\n" );
document.write( ", p = 4, focus(4,4), y = -4 directrix
\n" );
document.write( "
\n" );
document.write( " \n" );
