What is the degree of (15x^6+0x^8-4)?
Answer and explanation
Correct answer: 6
A term with coefficient 0 is a zero term, so it is not considered while finding the degree of a polynomial. Here, 0x^8 is a zero term; the remaining terms are 15x^6 and -4. The highest power of x among these terms is 6, so the degree is 6. Option 8 is a close distractor, but 0x^8 must not be counted. Exam tip: First remove all terms with zero coefficients before identifying the highest exponent.
