use compete the square technique
\n" ); document.write( " x^2-2x-1=0
\n" ); document.write( "x^2 -2x = 1
\n" ); document.write( "x^2 -2x +1 = 1 + 1
\n" ); document.write( "(x-1)^2 = 2
\n" ); document.write( "x-1 = square root(2)
\n" ); document.write( "x = 1 + square root(2)
\n" ); document.write( " \n" ); document.write( "
