f(x) =x^7+kx-2\r
\n" ); document.write( "\n" ); document.write( "*Plug the remainder in the 'f(X)'.\r
\n" ); document.write( "\n" ); document.write( "7=x^7+kx-2\r
\n" ); document.write( "\n" ); document.write( "*x-1=0 therefore, x=1. Substitue x for 1 in the equation.\r
\n" ); document.write( "\n" ); document.write( "7=1^7+1k-2
\n" ); document.write( "7= 1 + 1k - 2
\n" ); document.write( "7-1+2=k
\n" ); document.write( "8=k\r
\n" ); document.write( "\n" ); document.write( "k = 8
\n" ); document.write( "
\n" );
