# What is the name of the polynomial by degree and number of term of 6a^6+2a^5-2a^4+7?

The four terms are $6 {a}^{6}$, $2 {a}^{5}$, $- 2 {a}^{4}$ and $7$.
The terms are all scalar multiples of non-negative integer powers of $a$, so this is a polynomial in $a$.
The degree of the polynomial is the highest power of $a$ in any term, in this case $6$.
