x^2-3x+7=0
\n" ); document.write( "\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
\n" ); document.write( "x=(3+-sqrt[-3^2-4*1*7])/2*1
\n" ); document.write( "x=(3+-sqrt[9-28])/2
\n" ); document.write( "x=(3+-sqrt-19)/2
\n" ); document.write( "x=(3+-4.359i)/2
\n" ); document.write( "x=3+4.359i)/2
\n" ); document.write( "x=3/2+-4.359i/2
\n" ); document.write( "x=1.5+-2.18i ans.
