There is no need to use synthetic division to check if 0 is a zero of the polynomial. Every term with x in it will become zero leaving just the -4 at the end. So 0 is not a zero of P(x).

\n" ); document.write( "We will use synthetic division to check if -2 is a zero:
\n" ); document.write( "

\r\n" );
document.write( "-2 |  -1   0   6   2  -4\r\n" );
document.write( "----       2  -4  -4   4\r\n" );
document.write( "      ------------------\r\n" );
document.write( "      -1   2   2  -2   0\r\n" );
document.write( "

\n" ); document.write( "The remainder, which is in the lower right corner, is 0! So -2 is a zero of P(x). \n" ); document.write( "

\n" );
