Is this correct? I got this answer because 3 and 9 are both factors of 27. But because it says p to the second power multiplied by q to the second power I wrote p times q in parentheses and added pq to 3 times p times q multiplied by 9 times p times q. Sorry the explanation isnt the best.
Completely factor 9p²q² + 27pq.
9pq(pq + 3pq)
Almost! You have the correct GCF: 9pq.
Also, is indeed pq, but is 3, NOT 3pq.
