The given polynomial is:

\[
f(x) = 2x^5 + 3x^4 - 6x^2 + 4
\]

### To solve the problem:
1. **Zeros**: We need to find the values of \(x\) where \(f(x) = 0\).
2. **Maxima and Minima**: To find the local maximum and minimum, we need to find the critical points by calculating the first derivative, setting it equal to 0, and checking the second derivative.

Let me calculate these values for you step by step. I'll start with finding the first and second derivatives to identify critical points and zeros.The derivatives and critical points are as follows:

1. **First derivative** \( f'(x) = 10x^4 + 12x^3 - 12x \)
2. **Second derivative** \( f''(x) = 40x^3 + 36x^2 - 12 \)

### Critical points:
- One real critical point is at \(x = 0\). 
- The other critical points are complex, so they won't provide meaningful real maxima or minima.

### Zeros:
The zeros of the function are quite complex and cannot be easily expressed as simple numbers. They would require numerical methods to approximate, as indicated by the complex expressions involving the roots of the polynomial.

Next, I will approximate these zeros and critical points to find the maximum, minimum, and zeros rounded to the nearest tenth.### Results:

1. **Real critical points**:
   - \( x = 0 \)
   - \( x \approx 0.8 \) (rounded to the nearest tenth)

2. **Zeros** (Real solutions only):
   - \( x \approx -0.9 \) (rounded to the nearest tenth)

Most critical points and zeros are complex, but I've approximated the real solutions.

- **Maximum** at \(x \approx 0.8\) (evaluate \(f(x)\) to find the value).
- **Minimum** at \(x = 0\).

I'll now compute the function values at the real critical points to determine the max and min values.The function values at the real critical points are:

- **Minimum** at \(x = 0\), with \(f(0) = 4\).
- **Maximum** at \(x \approx 0.8\), with \(f(0.8) \approx 2.0\) (rounded to the nearest tenth).

### Final answers:
- **Maximum**: \((0.8, 2.0)\)
- **Minimum**: \((0, 4)\)
- **Zero**: \((-0.9, 0)\)
