The image you've uploaded shows a set of practice exercises involving conic sections. These are quadratic equations in two variables \( x \) and \( y \), and they need to be classified into categories such as ellipse, parabola, or hyperbola based on their general form. Here's the breakdown of the equations:

1. \( -2x^2 - 5y^2 + 4x - 8y + 1 = 0 \)
2. \( -x^2 + 4x - 3y + 2 = 0 \)
3. \( 3x^2 + 3y^2 - 8x + 4y - 2 = 0 \)
4. \( 2y^2 + 4x - 3 = 0 \)
5. \( -6x^2 + 3y^2 - 6x + 2y - 7 = 0 \)

To classify them into conic sections, here is a general approach:

### Step 1: Identify the coefficients
In general, the equation of a conic section is:
\[ Ax^2 + Bxy + Cy^2 + Dx + Ey + F = 0 \]
Where:
- If \( A \neq C \) and \( B = 0 \), it is a hyperbola.
- If \( A = C \), it is a circle (if \( A = C > 0 \)) or an ellipse (if \( A \neq C \)).
- If either \( A = 0 \) or \( C = 0 \) but not both, it is a parabola.

### Step 2: Classify the given equations
1. **Equation 1**: \( -2x^2 - 5y^2 + 4x - 8y + 1 = 0 \)
   - Here, \( A = -2 \) and \( C = -5 \). Since \( A \neq C \) and both are negative, this is an **ellipse**.

2. **Equation 2**: \( -x^2 + 4x - 3y + 2 = 0 \)
   - Here, \( A = -1 \) and there is no \( y^2 \) term, which makes it a **parabola**.

3. **Equation 3**: \( 3x^2 + 3y^2 - 8x + 4y - 2 = 0 \)
   - Here, \( A = 3 \) and \( C = 3 \), meaning \( A = C \), so it is a **circle**.

4. **Equation 4**: \( 2y^2 + 4x - 3 = 0 \)
   - Here, there is no \( x^2 \) term, and only \( y^2 \), so this is a **parabola**.

5. **Equation 5**: \( -6x^2 + 3y^2 - 6x + 2y - 7 = 0 \)
   - Here, \( A = -6 \) and \( C = 3 \), since \( A \neq C \) and their signs are different, this is a **hyperbola**.
