Can you plz find this witj equation

Answer= -4p^2r+3pr

Explanation:
Pr-6p^2r,3p^2r-2pr, 2pr-p^2r
Collect like terms so:
Pr-3p^2r-2pr,2pr-p^2
Pr-4p^2+2pr
-4p^2r+3pr

-3p^2r-p^2= -4p^r
Pr+2pr=3pr

I hope that explains it, if you still don’t understand it let me know and I’ll try explaining it better.
