Answer:
coefficient for k: -2
constant term?: -5
degree of the polynomial: 2
Step-by-step explanation:
The coefficient for k is the number that multiplies k. In this case:
7kn+2k^2-2k-2n-5+5n^2
The constant term is the number that doesn't multiply any variable. In this case:
7kn+2k^2-2k-2n-5+5n^2
The degree of a polynomial is the highest of the degrees of the polynomial's monomials. In this case, the highest monomials are:
7kn+2k^2-2k-2n-5+5n^2
all of them second degree
