What is the degree of (8x^5+0x^7-2x^3+6)?

Answer and explanation

Correct answer: 5

The degree of a polynomial is the greatest exponent among terms with non-zero coefficients. Here, the coefficient of \(0x^7\) is zero, so it does not count as a term of the polynomial. Among the remaining terms, \(8x^5\) has the greatest exponent, 5. Therefore, the degree is 5. Option 7 is a close distractor, but a term with a zero coefficient cannot determine the degree. Exam tip: First ignore all terms whose coefficients are zero before finding the highest power.
