Answer:
`5a^(3) - 5a^(2)`.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

|
`(a^(3) - 2a^(2)) - (3a^(2) - 4a^(3) )`

|

| To find the opposite of
`3a^(2) -4a^(3)`, find the opposite of each term.

\/

`a^(3) - 2a^(2) - 3a^(2) + 4a^(3)`

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

|

|Combine
`-2a^(2)` and
`-3a^(2)` to get
`-5a^(2)`.

\/
