What is the degree of (0x^5+8x^2-3x+4)?
Answer and explanation
Correct answer: 2
The coefficient of \(0x^5\) is zero, so it is not considered an actual term of the polynomial. The remaining polynomial is \(8x^2-3x+4\), whose highest power of \(x\) is \(2\). Therefore, its degree is \(2\). It is not \(5\) because the coefficient of \(x^5\) is zero. Exam tip: Remove all terms with zero coefficients before finding the degree.
