Answer 1

`-4p^3-3p^2-17p`

Explanation:

Adding a negative number is the same as subtracting a number. Using this logic, we can change the equation to equal this:

`-3p^3+5p^2-2p-p^3-8p^2-15p`

Combining like terms, we have negative 3p cubed minus another p cubed, which equals negative 4p cubed, we have 5p squared minus 8p squared, which equals negative 3p squared, and we have negative 2p minus 15p, which is negative 17p.
