Which polynomial has degree (9)?
Answer and explanation
Correct answer: 5x^9-x^2+7
The degree of a polynomial is the greatest exponent of the variable in any term with a non-zero coefficient. In option B, the term 5x^9 has exponent 9, so the polynomial 5x^9-x^2+7 has degree 9. Option A has degree 8, while the non-zero constant polynomial 30 has degree 0. Exam tip: identify the highest exponent of the variable after checking all terms.
