Answer
$2p^{3}+7p^{2}-3p$ is a cubic trinomial.
Work Step by Step
A standard polynomial is written in a decreasing order of power in a polynomial thus written in standard form it is $2p^{3}+7p^{2}-3p$
And this is a cubic trinomial because the highest power is 3 (cubic) and there are three terms present (trinomial).
