You can put this solution on YOUR website!
because it can't be factorized, we can use this formula:
\n" ); document.write( " $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( " $\"x+=+%28-4+%2B-+sqrt%28+4%5E2-4%2A1%2A%28-2%29+%29%29%2F%282%2A1%29+\"$
\n" ); document.write( " $\"x+=+%28-4+%2B-+sqrt%28+16%2B8+%29%29%2F2+\"$
\n" ); document.write( " $\"x+=+%28-4+%2B-+sqrt%28+24+%29%29%2F2+\"$
\n" ); document.write( " $\"x+=+%28-4+%2B-+sqrt%28+4%2A6+%29%29%2F2+\"$
\n" ); document.write( " $\"x+=+%28-4+%2B-+2%2Asqrt%28+6+%29%29%2F2+\"$
\n" ); document.write( " $\"x+=+-2+%2B-+sqrt%28+6+%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so,
\n" ); document.write( " $\"x1+=+-2+%2B+sqrt%28+6+%29\"$
\n" ); document.write( " $\"x2+=+-2+-+sqrt%28+6+%29\"$ \n" ); document.write( "

\n" );
