Answer
Standard form is $2c^4+6c^2-c$.
Degree is $4$.
Leading coefficient is $2$.
Type is Trinomial.
Work Step by Step
The given polynomial is $=6c^2+2c^4-c$
Standard form is $2c^4+6c^2-c$.
The greatest exponent of $c$ is $4$, so the degree of the polynomial is $4$.
Leading coefficient is $2$.
There are three terms, so the type of the polynomial is trinomial.
