Which statement is correct about x² + (2/3)x − √7?

Answer and explanation

Correct answer: It is a polynomial of degree 2

A polynomial may have any real coefficients, so both the fractional coefficient 2/3 and the irrational constant −√7 are permitted. The exponents of x are 2 and 1, while the constant has exponent 0. The greatest exponent is 2, so option C is correct. It is neither excluded by its coefficients nor the zero polynomial, since its terms are not all zero.
