Respuesta :
Since there are like terms, you can combine them
5a-2a = 3a
So, then you get
3a+9
Then you can factor to get a GCF of 3
3(a+3)
5a-2a = 3a
So, then you get
3a+9
Then you can factor to get a GCF of 3
3(a+3)
3a + 9
You subtract 2a from 5a, which equals 3a, but 9 is by itself, so it stays the same.
