Answer 2

Option C is correct

`3x^3-4x^2-10`

Explanation:

Like terms are those terms which have same variable to the same power.

Find the difference of the following:

`(3x^3-2x^2+4)-(2x^2+14)`

Remove the parenthesis we get;

`3x^3-2x^2+4-2x^2-14`

Combine like terms;

`3x^3-4x^2-10`

Therefore, the difference of
`(3x^3-2x^2+4)-(2x^2+14)` is,
`3x^3-4x^2-10`
