c thats the part o dont know wat to do next

OpenStudy (anonymous):
pq-2r+pr-2q
=> (pq-2q) + (pr -2r)

OpenStudy (anonymous):
what u will do next

OpenStudy (anonymous):
honestly im not sure

OpenStudy (anonymous):
take common q from the first part and r from the second
so we will get
q(p-2) +r(p-2)
therefore
(p-2)(q-r)
