\n" ); document.write( "\n" ); document.write( "This polynomial appears prime to me, but I am not sure if I am just forgetting to do something. Could I put it under a radical to get the cube roots of 27, 64, and z^3? Is that still factoring?

27 - 64z^3
\n" ); document.write( "(3)^3 - (4z)^3
\n" ); document.write( "(3 - 4z)(9 + 12z + 16z^2)
\n" ); document.write( "Check:
\n" ); document.write( "27 + 36z + 48z^2 - 36z - 48z^2 - 64z^3
\n" ); document.write( "27 - 64z^3
\n" ); document.write( "
\n" );
