You can first rewrite the problem without the parentheses:
Next, write the problem so that like terms are next to eachother:
Then, add or subtract (depending on the operation) like terms. Remember that variables with different exponents are not like terms. For example, 
and 
are like terms, but 
and 
are not like terms:

When subtracting one polynomial from another, you must use distributive property to distribute the – sign:
Now, rewrite the entire problem without the parentheses:
Reorganize the problem so that like terms are together. Remember that variables with different exponents are not like terms. For example, 
and 
are like terms, but, 
and 
are not like terms:
Combine the like terms by adding or subtracting (depending on the operation):

In previous problems, we used combining like terms to simplify. In this case, we first need to distribute in order to get rid of the parentheses.
Parentheses always indicate the operation multiplication. You multiply the number on the ouside of the parenthese by EVERY term inside the parentheses. In this case, you would multiply 
and 
After this first step, you should have: 
Then, we will combine like terms. Here, the like terms are 
and 
(they both have the variable 
and exponent 1). They combine into 
So the final answer is 
(There is not anything you need to combine the 12 with, so you just leave it as is.)
