Use the hint they gave you.... If
\n" ); document.write( "\"%28a%2B2b%29%5E3+=+a%5E3+%2B+8b%5E3+%2B+6ab%28a%2B2b%29\" then the expression you are to evaluate is
\n" ); document.write( "\"a%5E3+%2B+8b%5E3+=+%28a%2B2b%29%5E3+-+6ab%28a%2B2b%29\"

\n" ); document.write( "You are given the values of both (a+2b) and (ab) -- plug them into that equation and evaluate.
\n" ); document.write( "
\n" );
