Answer: The required simplified expression in standard form is
-2p^2-11p-35.

Step-by-step explanation: We are given to simplify the following equation and write the simplified expression in standard form :

E=-2(p+4)^2-3+5p~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

We will be using the following formula :

(a+b)^2=a^2+2ab+b^2.

The simplification of expression (i) is as follows :

$E\\\\=-2(p+4)^2-3+5p\\\\=-2(p^2+8p+16)-3+5p\\\\=-2p^2-16p-32-3+5p\\\\=-2p^2-11p-35.$

Thus, the required simplified expression in standard form is
-2p^2-11p-35.
