Factor completely: 64x^3+343
\n" ); document.write( "-----------------
\n" ); document.write( "It's the sum of 2 cubes.
\n" ); document.write( "\"a%5E3+%2B+b%5E3+=+%28a%2Bb%29%2A%28a%5E2+-+ab+%2B+b%5E2%29\"
\n" ); document.write( "Sub 4x for a, and 7 for b
\n" ); document.write( "--------------------
\n" ); document.write( "\"64x%5E3+%2B+343+=+%284x%2B7%29%2A%2816x%5E2+-+28x+%2B+49%29\"
\n" ); document.write( "--------------------------------
\n" ); document.write( "The difference of 2 cubes is similar:
\n" ); document.write( "\"a%5E3-b%5E3+=+%28a-b%29%2A%28a%5E2+%2B+ab+%2B+b%5E2%29\"
\n" ); document.write( "The difference of any 2 odd powers is also similar.
\n" ); document.write( "
\n" );
