Use the following formula to factor it.
\n" ); document.write( " $\"a%5E3-b%5E3=%28a-b%29%28a%5E2%2Bab%2Bb%5E2%29\"$
\n" ); document.write( "*****************************************
\n" ); document.write( " $\"64z%5E3-1\"$
\n" ); document.write( "= $\"%284z%29%5E3-1%5E3\"$
\n" ); document.write( "= $\"%284z-1%29%28%284z%29%5E2%2B%284z%29%2A1%2B1%5E2%29\"$
\n" ); document.write( "= $\"%284z-1%29%2816z%5E2%2B4z%2B1%29\"$
\n" ); document.write( " \n" ); document.write( "
