What is the degree of the polynomial (x^2+x^7+4x)?
Answer and explanation
Correct answer: 7
The degree of a polynomial is the greatest exponent of its variable. The terms are x^2, x^7, and 4x, whose exponents of x are 2, 7, and 1 respectively. The greatest exponent is 7, so the degree is 7. The number 4 is a coefficient, not an exponent. Exam tip: changing the order of terms does not change the degree of a polynomial.
