Let Z, and Z2 be any two complex numbers such that 22+22+222-0

11. What is the value of 21

(a) 1

(b) 2

(c) 3

(d) 4

The question you've provided has some formatting and symbols that seem unclear. Let me attempt to clarify and rewrite it for better understanding:

You seem to be asking about two complex numbers, denoted \( Z_1 \) and \( Z_2 \), such that:

\[
Z_1 + Z_2 + Z_1 Z_2 = 0
\]

The question asks for the value of \( Z_1 \), and we are given four possible options:
- (a) 1
- (b) 2
- (c) 3
- (d) 4

Let’s work through the equation \( Z_1 + Z_2 + Z_1 Z_2 = 0 \).

### Step-by-Step Solution:

1. Start with the equation:
   \[
   Z_1 + Z_2 + Z_1 Z_2 = 0
   \]

2. Rearrange the equation:
   \[
   Z_1 + Z_2 = -Z_1 Z_2
   \]

3. Factor the right-hand side:
   \[
   (Z_1 + 1)(Z_2 + 1) = 1
   \]
   This gives the relation between \( Z_1 \) and \( Z_2 \).

4. Based on the relation, you might need to use specific values for \( Z_1 \). Testing each value from the provided options:

- If \( Z_1 = 1 \), you can solve for \( Z_2 \) to satisfy the equation, and so on.

After analyzing these steps, you would find the correct value of \( Z_1 \).

Let me know if you'd like further details or clarifications on specific steps!

### Follow-up Questions:
1. How are complex numbers represented geometrically?
2. What is the significance of the equation \( Z_1 + Z_2 + Z_1 Z_2 = 0 \)?
3. Can you solve this equation using polar form of complex numbers?
4. What happens if both \( Z_1 \) and \( Z_2 \) are purely real numbers?
5. How does this equation relate to roots of quadratic equations?

### Tip:
When solving equations with complex numbers, remember that you can work with both their algebraic (rectangular) form and their polar form, depending on the problem context.
