What is the degree of (0x^7+4x^3-2x+6)?

Answer and explanation

Correct answer: 3

The term \(0x^7\) is zero, so it does not contribute to the degree of the polynomial. In the remaining expression, \(4x^3-2x+6\), the highest power of \(x\) is \(3\). Therefore, its degree is \(3\). Choosing \(7\) would be incorrect because its coefficient is zero. Exam tip: Remove terms with zero coefficients before finding the degree.
