See explanation.

Explanation:

To write a polynomial in a standard form you have to order its terms by the decreasing powers of the variable and reduce the like terms if possible.

$-7x^2-x^3+x+5+2=-x^3-7x^2+x+5+2=$

$=-x^3-7x^2+x+7$

The last expression is in the standard form. The highest power, to which $x$ is raised is $3$ , and it has $4$ terms, so it is a quadrinomial of the third degree.
