I believe the answer is 4x + 8. you multiply 4 by x which makes 4x. Than you multiply 4 by 2, making 8. 
This problem appears to be linked with the Distributive Property. The Distributive Property allows any outside number/variable of the parenthesis to multiply with all inside numbers/variables within the parenthesis.

For example:

2(1 + 3)
2(1) + 2(3)
2 + 6
8.

With our definition, rule, and example, we are ready to solve.

4(x + 2)
Multiply the outside number (4) by all inside numbers/variables (x + 2).
4(x) + 4(2)
4x + 8.
If this is not solving for x, this is your answer.

If we are solving for x, we need to get 4x by itself and then simplify if possible.

4x + 8 = 0
Remember, what you do to one side of the equation you must do to the other.
Subtract 8 from both sides.
4x = -8
Divide both sides by 4.

4x / 4 = x
-8 / 4 = -2
X = -2

Your answers are:

4x + 8 if simplifying the expression.
x = -2 if we are solving for x.

I hope this helps!
