12a + 6b + 9a + 14b =(12a + 9a) + (6b + 14b) =21a + 20b
12a + 6b + 6c = 6(2a + b + c)
It is:12a
When factored it is: 12(A+b)
It is 6*(b + 4)
11b + 6b = 17b
6b+5a-4b+3a= ? Rearrange it as 5a+3a+6b-4b = 8a+2b
3a+6b are two terms of an expression
6b+b+b is the same as 6b+1b+1b you can add the numbers together if the variables are the same. 6b+1b+1b=8b
The polynomial IS b2 - 6b + 8.
6(a+b)
