What is the degree of (3x^8-4x^5+2x^2-1)?

Answer and explanation

Correct answer: 8

The degree of a polynomial is the greatest exponent of the variable in any term with a non-zero coefficient. In the given polynomial, the exponents of x are 8, 5, 2, and 0. The greatest exponent is 8, so its degree is 8. The number 5 is only the exponent in the term 4x^5, not the degree of the polynomial. Exam tip: Check the exponents of the variable in all terms before choosing the degree.
