$\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( " $\"x+=+%28-%28-1%29+%2B-+sqrt%28+%28-1%29%5E2-4%2A%281%29%2A%284%29%29%29%2F%282%2A1%29\"$
\n" ); document.write( "applying the direct formula.
\n" ); document.write( "we get, \r
\n" ); document.write( "\n" ); document.write( " $\"x+=+1+%2B-+sqrt%2815%29\"$ \r
\n" ); document.write( "\n" ); document.write( "that is $\"a+=+1%2Bsqrt%2815%29\"$
\n" ); document.write( "and $\"b+=+1-sqrt%2815%29\"$
\n" ); document.write( "then u get::::: b/a + a/b =
\n" ); document.write( "

\n" ); document.write( "u need to solve this like this :

\n" ); document.write( "so,
