According to Wikipedia, a polynomial is an expression consisting of indeterminates (also called variables) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

The first one is just a mess.

The second one fits all conditions.

The third one has a variable exponent.

The fourth one has a negative exponent.

Thus the only one that is a polynomial is the second one, or **x^4 - 2**.
