You can only add things that are the same eg
2 apples + 3 oranges + 4apples
= 6 apples + 3 oranges.
In your example you have
2 of x³ and 2 of x
x³ and x are different things so 2x³ + 2x cannot be simplified apart from taking a Common Factor as follows:-
2x³ + 2x = 2x.(x² + 1)
Don`t give in--you`ll make it!

no, they cannot be added. They can only be added if the powers and the alphabet is identical. In this senario, you can draw out the commn factor, x or in the later cae, x^2

they are not like terms.
i guess you could factor out 2x, it depends how particular your teacher is...
