Which expression is not a polynomial in x because the variable is in the denominator?

Answer and explanation

Correct answer: 7/(x - 3)

The governing concept is the required form of a polynomial in x. Every exponent of x in a polynomial must be a non-negative integer, while numerical coefficients may be any real numbers. Options A and D clearly satisfy this rule. Option C also satisfies it because √2 is only a constant coefficient multiplying x^3; the radical does not contain x. In option B, 7/(x - 3), the variable x occurs in the denominator. This makes the expression rational rather than polynomial, and it is undefined at x = 3. Hence option B is correct. The presence of a radical constant in option C is not a violation, and a polynomial may contain several terms and constant terms.
