\n" ); document.write( "\n" ); document.write( "\"64x%5E3%2B27\" Start with the given expression.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%284x%29%5E3%2B%283%29%5E3\" Rewrite \"64x%5E3\" as \"%284x%29%5E3\". Rewrite \"27\" as \"%283%29%5E3\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%284x%2B3%29%28%284x%29%5E2-%284x%29%283%29%2B%283%29%5E2%29\" Now factor by using the sum of cubes formula. Remember the sum of cubes formula is \"A%5E3%2BB%5E3=%28A%2BB%29%28A%5E2-AB%2BB%5E2%29\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%284x%2B3%29%2816x%5E2-12x%2B9%29\" Multiply\r

\n" ); document.write( "\n" ); document.write( "-----------------------------------\r
\n" ); document.write( "\n" ); document.write( "Answer:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"64x%5E3%2B27\" factors to \"%284x%2B3%29%2816x%5E2-12x%2B9%29\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In other words, \"64x%5E3%2B27=%284x%2B3%29%2816x%5E2-12x%2B9%29\"
\n" ); document.write( " \n" ); document.write( "
