What kind of expression is √x + 2x?

Answer and explanation

Correct answer: Not a polynomial

The governing definition says that a polynomial in x can contain only non-negative integer powers of x, such as 0, 1, 2, and 3. Rewrite the radical as √x = x^(1/2). Although the term 2x has the valid integer power 1, the term x^(1/2) has a fractional power. A single fractional exponent is enough to make the complete expression non-polynomial. Therefore option C is correct. It is not linear because the radical term cannot be treated as an ordinary first-degree term, and it is not quadratic because no x² term is present. It is not constant because x appears in both terms. The coefficient 2 is allowed; the fractional exponent is the decisive issue.
