no. x² and x are not like terms.
suppose x = 5. then x² = 25
x² + x = 25 + 5 = 30 but
x^3 = 125 and
2x² = 2(25) = 50

No.
In general, you may not add terms that are raised to different powers, unless you have additional information regarding the value of "x".
x^2 + x is the simplest way to express the polynomial.

in order for terms to be added they must have to same exponent that is why you can add 3x^1 and 4x^1 but not 4x^1 and 4x^2

You can't. It would be just x^2 + x.

No, because they are not "like terms."

No you cannot. they are not the same variable factor
