  1. -8n^2-16m


  2. First thing to do is clear the parentheses.

    2m - 2n^2 - 6n^2 - 18m

    Next collect like terms.  That is, the n^2 terms, the n terms and the m terms.

    2m - 18m - 2n^2 - 6n^2

    -16m - 8n^2

    That's about it.  Unless you want the higher order term (squared term) first:

    -8n^2 - 16m

  3. -8nsquared - 16 m

    which = nsquared + 2m I believe
