What is the degree of (4x^2-1+6x^5)?
Answer and explanation
Correct answer: 5
The degree of a polynomial is the greatest exponent of the variable with a non-zero coefficient. In the given polynomial, the exponents of x are 2, 0, and 5. The greatest exponent is 5, so its degree is 5. Option 2 is not correct because it is only the degree of the term 4x^2. Exam tip: Arrange the polynomial in descending powers and identify the highest exponent to find its degree quickly.
