Which statement is correct about \(4x^2+\frac{3}{7}x-6\)?

Answer and explanation

Correct answer: It is a polynomial because all powers of the variable are non-negative integers.

\(4x^2+\frac{3}{7}x-6\) is a polynomial because the powers of \(x\) are \(2\), \(1\), and \(0\), all of which are non-negative integers. Polynomial coefficients may be fractional or negative, so neither \(\frac{3}{7}\) nor the constant term \(-6\) makes it invalid. A zero polynomial has every coefficient equal to zero, which is not the case here. Exam tip: to identify a polynomial, first check the exponents of the variable.
