\n" ); document.write( " $\"+-2i+and+sqrt%2810%29+\"$ are the roots of function P(x)=0\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "P(x) has rational coefficients. The conjugates are 2i and - $\"sqrt%2810%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Complex roots of polynomials with real coefficients come in conjugate pairs. \r
\n" ); document.write( "\n" ); document.write( "Therefore , 2i and - $\"sqrt%2810%29\"$ are the other roots of the function .
\n" ); document.write( " \n" ); document.write( "
