What is the degree of (4x^8-3x^6+x^2-5)?

Answer and explanation

Correct answer: 8

The degree of a polynomial is the highest power of the variable among terms with non-zero coefficients. Here, the powers of x are 8, 6, and 2, while the constant term -5 has degree 0. The greatest power is 8, so the correct answer is 8. Option 6 is only the power in the term -3x^6, not the degree of the whole polynomial. Exam tip: Ignore zero-coefficient terms and identify the highest exponent of the variable.
