What is the degree of (-x^4+8x^2-6)?
Answer and explanation
Correct answer: 4
The degree of a polynomial is the greatest exponent of the variable in any term with a non-zero coefficient. Here, the exponents of the terms are 4, 2, and 0, so the greatest exponent is 4. The negative sign in the coefficient of
y does not affect the degree. Exam tip: First write the polynomial in simplified form, then identify the highest power of the variable.
