To solve the problem, we need to show that \( 1 + \left| \frac{b}{a} \right| + \frac{c}{a} > 0 \) given that the quadratic equation \( ax^2 + bx + c = 0 \) has two real roots \( \alpha \) and \( \beta \) such that \( \alpha > -1 \) and \( \beta > 1 \). ### Step-by-Step Solution: 1. **Understanding the Roots**: Since the quadratic equation has real roots, the discriminant must be non-negative: \[ D = b^2 - 4ac \geq 0 ...
