Answer:

$-2p^2-11p-35$

Step-by-step explanation:

$-2(p+4)^2-3+5p$

First we square the parenthesis. Apply FOIL method to multiply

$(p+4)^2= (p+4)(p+4)= p^2 + 4p+4p+16= p^2+8p+16$

$-2(p^2+8p+16) -3+5p$

distribute -2 inside the parenthesis

$-2p^2-16p-32-3+5p$

Now combine like terms

$-2p^2-11p-35$
