We start with the expression:
$$
2x^2 + 4x - 2
$$
Substitute $$ x = -2 $$ into the expression:
$$
2(-2)^2 + 4(-2) - 2
$$
Evaluate $$(-2)^2$$, which is:
$$
(-2)^2 = 4
$$
Then the expression becomes:
$$
2(4) + (-8) - 2
$$
Multiply:
$$
8 - 8 - 2
$$
Combine the terms:
$$
8 - 8 = 0 \quad \text{and} \quad 0 - 2 = -2
$$
Thus, the value of the expression when $$ x = -2 $$ is:
$$
-2
$$

The correct answer is A.
The value of the expression when $$ x = -2 $$ is -2, so the correct answer is A.
