\n" );
document.write( "x^2 - 8x - 20 = 0   |Completing the square
\n" );
document.write( "(x-4)^2 -16 - 20 = 0  |Note:(x-4)^2 -16 = (x^2-8x+16) -16 = x^2-8x
\n" );
document.write( "  (x-4)^2 = 36
\n" );
document.write( "  (x-4) = ± 6
\n" );
document.write( "   x-4 = 6
\n" );
document.write( "     x = 10
\n" );
document.write( "   x-4 = -6
\n" );
document.write( "     x = -2 \n" );
