Answer:
for the first one, the solution is -pq x (3q-p) for the second question, the solution is p²q-3pq²
Step-by-step explanation:
for the first question:
-3pq²+p²q
factor out -pq from the expression
solution pq x (3q-p)
for the second question:
remove unnecessary parenthesis
2p²q-3pq²+q^3-(p²q-q^3)
when there is a "-" in front of the parenthesis, change the sign of each term in parenthesis
2p²q-3pq²+q^3-(p²q-q^3)
then, eliminate the opposites
2p²q-3pq²-p²q
collect the terms
p²q-3pq²
finally, you got your answer,
p²q-3pq²
I hope this helped!
