You can put this solution on YOUR website!
These are NOT like terms, so you CANNOT combine them.\r

\n" ); document.write( "\n" ); document.write( "You leave them as is. If you want to factor this, then\r

\n" ); document.write( "\n" ); document.write( " $\"x%5E4+%2B+x%5E7+=+x%5E4%281+%2B+x%5E3%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "then you factor $\"1%2Bx%5E3\"$ to get $\"%281%2Bx%29%281+-+x+%2B+x%5E2%29\"$ (sum of cubes rule) to get this final answer\r
