Answer
Standard form : $d^2-3d+9$.
Degree : $2$.
Leading coefficient : $1$.
Type : trinomial.
Work Step by Step
The given polynomial is
$=9+d^2-3d$
Standard form is $d^2-3d+9$.
The greatest exponent of $d$ is $2$, so the degree of the polynomial is $2$.
Leading coefficient is $1$.
There is three term, so the type of the polynomial is trinomial.
