Answer :
For #3:
The common factor here is 2p, because 2p is the greatest term that can get into both of the numbers:
So we write:
2p(-3p^4 - 5)
So when we distribute we get:
-6p^5 - 10p
The common factor here is 2p, because 2p is the greatest term that can get into both of the numbers:
So we write:
2p(-3p^4 - 5)
