To simplify the expression $2(x + 2)$, distribute the $2$ to each term inside the parentheses:

$2(x + 2) = 2 \cdot x + 2 \cdot 2 = 2x + 4$

So, the simplified form is:

$2x + 4$

Would you like more details on the steps or have any questions?

Here are some related questions:

1. What if we had $3(x + 2)$ instead?
2. How would this change if we added an exponent, like $2(x + 2)^2$?
3. What if the expression were $2(x - 2)$ instead?
4. How does distributing work in expressions like $2(3x + 4)$?
5. How would we solve if $2(x + 2) = 10$?

Tip: When simplifying, always apply distribution carefully to each term inside the parentheses.
