If `p , qr` are real and `p!=q` , then show that the roots of the equation `(p-q)x^2+5(p+q)x-2(p-q=0` are real and unequal.

Explanation

To show that the roots of the equation \((p - q)x^2 + 5(p + q)x - 2(p - q) = 0\) are real and unequal, we will use the concept of the discriminant of a quadratic equation.

### Step-by-Step Solution:

1. **Identify the coefficients**:
The given quadratic equation is in the form \(Ax^2 + Bx + C = 0\), where:
- \(A = p - q\)
- \(B = 5(p + q)\)
