Find the coefficient of `x^8` in the expansion of`(x^2-1/x)^(10)`

Explanation

To find the coefficient of \( x^8 \) in the expansion of \( (x^2 - \frac{1}{x})^{10} \), we can use the Binomial Theorem.

### Step-by-step Solution:

1. **Identify the Binomial Expansion**:
The expression can be expanded using the Binomial Theorem, which states that:
\[
(a + b)^n = \sum_{r=0}^{n} \binom{n}{r} a^{n-r} b^r
