\n" ); document.write( "\"8x%5E3%2B27y%5E6\" Start with the given expression.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%282x%29%5E3%2B%283y%5E2%29%5E3\" Rewrite \"8x%5E3\" as \"%282x%29%5E3\". Rewrite \"27y%5E6\" as \"%283y%5E2%29%5E3\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%282x%2B3y%5E2%29%28%282x%29%5E2-%282x%29%283y%5E2%29%2B%283y%5E2%29%5E2%29\" Now factor by using the sum of cubes formula. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "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( "\"%282x%2B3y%5E2%29%284x%5E2-6xy%5E2%2B9y%5E4%29\" Multiply\r
\n" ); document.write( "
\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 \"8x%5E3%2B27y%5E6\" factors to \"%282x%2B3y%5E2%29%284x%5E2-6xy%5E2%2B9y%5E4%29\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In other words, \"8x%5E3%2B27y%5E6=%282x%2B3y%5E2%29%284x%5E2-6xy%5E2%2B9y%5E4%29\"
