Answer:
4
Explanation:
The degree of a polynomial is the highest power of its variables. For example, in the polynomial 4x^3 + 2x^2 - 5x + 7, the degree is 3 because x^3 is the term with the highest degree. The degree of a constant polynomial, such as 7, is 0. In general, if a polynomial has n terms, its degree is the degree of its leading term (the term with the highest degree).
