complete the square
\n" ); document.write( "x^2 - x =-8
\n" ); document.write( "x^2 - x =-32/4
\n" ); document.write( "x^2 - x +1/4=1/4-32/4
\n" ); document.write( "(x-1/2)^2=-31/4
\n" ); document.write( "x = 1/2 (1+i sqrt(31))
\n" ); document.write( "x = 1/2 (1-i sqrt(31))
\n" ); document.write( " \n" ); document.write( "

\n" );
