Is (\pi x^2-5x+1) a polynomial in (x)?

Answer and explanation

Correct answer: Yes, because (\pi) is a real number and the powers are valid

A polynomial in \\(x\\) may have real-number coefficients, and \\(\\pi\\) is a real number. The expression \\(\\pi x^2-5x+1\\) has powers \\(2\\), \\(1\\), and \\(0\\), all of which are non-negative whole numbers. Its coefficients are \\(\\pi\\), -5, and 1, so it satisfies the definition of a polynomial in \\(x\\).

Thus option B is correct. The symbol \\(\\pi\\) is not an obstacle; irrational real numbers may be coefficients. Also, having three terms or containing \\(x^2\\) is completely allowed. A non-polynomial example would contain a negative or fractional power of \\(x\\), or place \\(x\\) in a denominator. Neither issue occurs here.
