Simplifying
In order to simplify this expression, I am going to use a property called the distributive property. It states that:
where a,b, and c are terms.
Basically, the idea is that you take a term 'a' and multiply it by the terms inside the parentheses (the terms are b and c).. Let's see how this works.
We're asked to simplify the expression:

By using the property,

Therefore, our answer is 3 + 27u.
