What is the degree of (0x^6+5x^3-2)?
Answer and explanation
Correct answer: 3
The coefficient of 0x^6 is 0, so it is a zero term and is not considered when finding the degree. The remaining polynomial is 5x^3-2, whose highest power of x is 3. Therefore, the correct answer is 3. Choosing 6 would be incorrect because the coefficient of x^6 is zero. Exam tip: Remove terms with zero coefficients before identifying the highest exponent.
