In which option is the degree of the polynomial in (x) stated incorrectly?

Answer and explanation

Correct answer: degree \(2\)

The degree of a polynomial is the greatest exponent of the variable having a non-zero coefficient. In \(x^4+x^2\), the greatest power of \(x\) is \(4\), so its degree is \(4\), not \(2\). In option C, \(9\) is a non-zero constant polynomial, whose degree is \(0\). Exam tip: simplify the polynomial first, then identify the highest power of \(x\).
