What is the degree of (x^0+2x^3-8x)?
Answer and explanation
Correct answer: 3
Here, x^0=1, so the polynomial can be written as 1+2x^3-8x. The highest exponent of x with a non-zero coefficient is 3; therefore, its degree is 3. The number 8 is a coefficient, not an exponent. Exam tip: Simplify the polynomial first, then identify the highest power of x.
