Let’s break it down! First, you’re adding and inside the parentheses, which gives you . Then, you multiply by . So, . The final answer is !

Now, here’s a fun fact: Did you know that the distributive property plays a key role in making these calculations easier? Instead of solving it in two steps, you could also think of it as , which would give you the same result but can be handy for mental math or larger numbers!
