Answer

$-4p^3+10p^2+5p-5$

Work Step by Step

Removing the grouping symbols and then combining like terms, the given expression, $ (3p^2+2p-5)+(7p^2-4p^3+3p) ,$ simplifies to \begin{array}{l}\require{cancel} 3p^2+2p-5+7p^2-4p^3+3p \\\\= -4p^3+(3p^2+7p^2)+(2p+3p)-5 \\\\= -4p^3+10p^2+5p-5 .\end{array}
