What is the degree of (2x^4+0x^3+0x^2+6)?
Answer and explanation
Correct answer: 4
The degree of a polynomial is the highest power of the variable in a term with a non-zero coefficient. Here, the term 2x^4 has power 4. The terms 0x^3 and 0x^2 are zero terms, so they do not affect the degree. The constant term 6 has power 0. Therefore, the degree of the polynomial is 4. Exam tip: Ignore terms with zero coefficients before finding the degree.
