It multiplies out as: 12a-12+2 = 12a-10
When factored it is: 12(A+b)
It is: 12a+2 when simplified
12a- 6a + a = 7a Since they all have the same variable, you can simply add and subtract 12-6 = 6 6+1 = 7
13a
12*a+8 =12a+8
It multiplies out as: 12a-12+2 = 12a-10
8a+4a=144 12a=144 12a/12=144/12 A=144
When factored it is: 12(A+b)
12a + 6b + 9a + 14b =(12a + 9a) + (6b + 14b) =21a + 20b
It is: 12a+2 when simplified
12a + a - 3a = 10a
12a- 6a + a = 7a Since they all have the same variable, you can simply add and subtract 12-6 = 6 6+1 = 7
13a
18
That depends what the value of a is.
