Solve z

2 + 2z̅+ 2 = 0 for z, where z ∈ C.

To solve for \( z \) in the equation \( 2 + 2\overline{z} + 2 = 0 \) where \( z \in \mathbb{C} \), we can proceed as follows:

1. Simplify the given equation:
   \[
   2 + 2\overline{z} + 2 = 0
   \]
   \[
   4 + 2\overline{z} = 0
   \]
   \[
   2\overline{z} = -4
   \]
   \[
   \overline{z} = -2
   \]

2. Recall that if \( z = a + bi \) (where \( a, b \in \mathbb{R} \)), then the complex conjugate \( \overline{z} = a - bi \). Therefore:
   \[
   \overline{z} = -2 \implies a - bi = -2
   \]

3. Since \( a \) and \( b \) are real numbers, we can equate the real and imaginary parts separately. This implies:
   \[
   a = -2 \quad \text{and} \quad -bi = 0
   \]

4. Solving these equations, we get:
   \[
   a = -2 \quad \text{and} \quad b = 0
   \]

5. Hence, \( z = a + bi \) becomes:
   \[
   z = -2 + 0i
   \]
   \[
   z = -2
   \]

So the solution to the equation \( 2 + 2\overline{z} + 2 = 0 \) is \( z = -2 \).
