What is the degree of (0x^9+6x^4-5x+3)?
Answer and explanation
Correct answer: 4
The coefficient of 0x^9 is 0, so it is a zero term and does not determine the degree of the polynomial. Among the remaining non-zero terms, 6x^4 has the highest exponent, 4. Therefore, the degree is 4. Choosing 9 would be incorrect because the coefficient of x^9 is zero. Exam tip: Remove terms with zero coefficients before finding the degree.
