What is the degree of (0x^5+0x^2+9x-6)?
Answer and explanation
Correct answer: 1
The terms 0x^5 and 0x^2 are zero, so they do not contribute to the polynomial. The expression becomes 9x-6, in which the highest power of x is 1. Therefore, its degree is 1. Choosing 5 is incorrect because the coefficient of x^5 is zero. Exam tip: Remove all terms with zero coefficients before finding the degree.
