\"a%5E6++-+2+%2B+a%5E3\"
\n" ); document.write( "\"a%5E6+%2B+a%5E3+-+2\"
\n" ); document.write( "Make this substitution:
\n" ); document.write( "\"z+=+a%5E3\"
\n" ); document.write( "Then change the expression to:
\n" ); document.write( "\"z%5E2+%2B+z+-+2\"
\n" ); document.write( "By inspection, I see:
\n" ); document.write( "\"%28z+%2B+2%29%28z+-+1%29\"
\n" ); document.write( "Now substitute again
\n" ); document.write( "\"%28a%5E3+%2B+2%29%28a%5E3+-+1%29\" answer
\n" ); document.write( "
\n" );
