Which option gives a correct example according to the definition of a polynomial?

Answer and explanation

Correct answer: x² + 4x + 4, because the powers are 2, 1 and 0

By definition, a polynomial in x is a finite expression in which the exponent of x in every term is a non-negative integer. Option A, x² + 4x + 4, has powers 2, 1 and 0, so it satisfies the definition and is a quadratic polynomial. Option B is not a polynomial because −2 is a negative exponent. Option C is not a polynomial because √x represents x¹ᐟ², a fractional exponent. Option D is not a polynomial because 1/x represents x⁻¹; the variable effectively occurs in the denominator. The reasons stated in the distractors do not establish polynomial status. Therefore, option A is the unique correct example.
