Answer
Standard form is $x^3+2.8x$.
Degree is $3$.
Leading coefficient is $1$.
Type is Binomial.
Work Step by Step
The given polynomial is $=2.8x+x^3$
Standard form is $x^3+2.8x$.
The greatest exponent of $x$ is $3$, so the degree of the polynomial is $3$.
Leading coefficient is $1$.
There are two terms, so the type of the polynomial is binomial.
