Which option correctly identifies a polynomial?

Answer and explanation

Correct answer: x² + √3x + 5

The governing concept is the definition of a polynomial in x. Every exponent of the variable must be a non-negative integer: 0, 1, 2, 3, and so on. In option A, the powers of x are 2, 1, and 0, so x² + √3x + 5 is a polynomial. The coefficient √3 is a fixed real number, and an irrational coefficient is permitted; coefficients do not have to be rational. Option B contains √x = x^(1/2), a fractional exponent. Option C contains x⁻², a negative exponent. Option D can be rewritten as 1 + x⁻¹, so it also contains a negative power. Therefore option A alone satisfies the polynomial definition.
