If `alpha and beta` are the zeroes of the quadratic polynomial `f(x)=x^2+x-2,` find the value of `1/alpha-1/beta`.

Explanation

To solve the problem step by step, we will find the roots of the quadratic polynomial \( f(x) = x^2 + x - 2 \) and then calculate the value of \( \frac{1}{\alpha} - \frac{1}{\beta} \), where \( \alpha \) and \( \beta \) are the roots of the polynomial.

### Step 1: Identify the polynomial
The given polynomial is:
\[ f(x) = x^2 + x - 2 \]
