These are NOT like terms, so you CANNOT combine them.

You leave them as is. If you want to factor this, then

x%5E4+%2B+x%5E7+=+x%5E4%281+%2B+x%5E3%29

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

x%5E4%281+%2B+x%29%281+-+x+%2B+x%5E2%29
