You can put this solution on YOUR website!
In place of x you simply put -3 and for the second part 5
p%28-3%29=2%28-3%29%5E4%2B3%28-3%29%5E3-9%28-3%29%5E2%2B16%28-3%29%2B13
So you get
p%28-3%29=2x81%2B3%28-27%29-9%289%29%2B%28-48%29%2B13
p%28-3%29=162%2B%28-81%29-%2881%29-48+%2B13
p%28-3%29=162-81-81-48+%2B13
Pretty sure you can simplify this :)
Similary, you now replace the X with 5
