Which statement is true about the polynomial –10m4n3 + 8m2n6 + 3m4n3 – 2m2n6 – 6m2n6 after it has been fully simplified?
a. it is a monomial with a degree of 4.
b. it is a monomial with a degree of 7.
c. it is a binomial with a degree of 6.
d. it is a binomial with a degree of 8.

The polynomial consists of 5 monomials of form and

To simplify this polynomial, group terms that are of the same form:

1.

2.

Then the simpliest form of the polynomial is You can see that only one monomial left and this monomial has a degree of 4+3=7.

correct option is B (a monomial with a degree of 7).

just needed some points but try socratic
