The provided image contains a quadratic equation and asks to determine the type of solutions based on the discriminant. The equation is:

\[
2x^2 + 3x + 2 = 0
\]

Let's solve this step by step.

### 1. General form of a quadratic equation:
The general form is:

\[
ax^2 + bx + c = 0
\]

In this case:
- \( a = 2 \)
- \( b = 3 \)
- \( c = 2 \)

### 2. Discriminant (\( \Delta \)):
The discriminant formula is:

\[
\Delta = b^2 - 4ac
\]

Substituting the values of \( a \), \( b \), and \( c \):

\[
\Delta = 3^2 - 4(2)(2) = 9 - 16 = -7
\]

### 3. Analyzing the discriminant:
- If \( \Delta > 0 \), the equation has two distinct real roots.
- If \( \Delta = 0 \), the equation has one real repeated root.
- If \( \Delta < 0 \), the equation has two distinct complex roots.

Since \( \Delta = -7 \), which is less than 0, the equation has two distinct complex (imaginary) solutions.

Thus, the correct answer is:

\[
\boxed{3} \, \text{(異なる2つの虚数解をもつ)} \, \text{Two distinct complex solutions}.
\]
