since f(x) =0\r
\n" ); document.write( "\n" ); document.write( "x^3-x = 0
\n" ); document.write( "x(x^2-1)=0
\n" ); document.write( "x=0 and,
\n" ); document.write( "x^2-1=0
\n" ); document.write( "x^2=1
\n" ); document.write( "x=1 or -1\r
\n" ); document.write( "\n" ); document.write( "the real values of x are -1,0,1
\n" ); document.write( "
\n" ); document.write( "
\n" );
