consider the polynomial:
7kn + 2k^2 - 2k - 2n - 5 + 5n^2
how many terms are there?
what is the coefficient for k?
what is the degree of the polynomial?
what is the constant term?
There are five terms in the polynomial.
The coefficient for k is given by 7n - 2.
The degree of the polynomial is determined by the highest power of the variable(s) involved, in this case k and n. The highest degree term in the polynomial is 5n^2, so the degree of the polynomial is 2.
The constant term is the term without any variable factors, in this case -5.
